The efficient solar-to-energy (STE) technique, relying on the advanced semiconductor materials, is critically important for addressing the global energy crisis. The ideal semiconductors for efficient STE conversion should exhibit high electronic dimensionality guided by the advanced concept. Herein, electronic dimensionality refers to the connectivity of atomic orbitals in the frontier electronic bands, which directly influence the charge transport anisotropy and carrier effective masses. The advanced three-dimensional (3D) electronic dimensionality enables the isotropic and efficient charge carrier transport, a feature of high-STE-performance semiconductors. Bournonite CuPbSbS3, a recently emerging metal sulfide (MS) material, features the 3D electronic dimensionality, direct bandgap of approximately 1.3 eV, and defect-tolerant feature, rendering it a highly promising candidate for high-performance STE systems. This review begins by outlining the design principles and fundamental semiconductor characteristics of CuPbSbS3, and then offers a comprehensive survey of its exploration process and applications across the STE spectrum, from photovoltaics to photocatalysis. Finally, perspective on the challenges and opportunities for future research on bournonite CuPbSbS3 are provided.

Weak non-covalent interactions, including hydrogen bonds, π–π stacking, and the diverse family of σ-hole interactions (halogen, chalcogen, pnictogen, tetrel, osme, and matere bonds), govern the structure, stability, and properties of molecular crystals. Solid-state Nuclear Magnetic Resonance (SSNMR) spectroscopy provides an unparalleled means of probing these interactions at the atomic level by directly sensing local electronic environments, independent of long-range order. This review surveys recent advances (approximately since 2020) in SSNMR methodologies for detecting, characterizing, and quantifying weak interactions in molecular solids. Particular emphasis is placed on developments in high-field and ultrafast magic-angle spinning (MAS) instrumentation, as well as novel pulse sequences that enhance access to key nuclei involved in non-covalent bonding. SSNMR observables, such as chemical shifts, dipolar and J couplings, quadrupolar parameters, and relaxation rates, are shown to provide quantitative insight into the interaction strength, geometry, and dynamics of hydrogen-bonded, π-stacked, and σ-hole-bonded systems. The review also discusses the synergistic integration of SSNMR with diffraction (single-crystal and powder X-ray diffraction, electron diffraction) and computational methods (Crystal Structure Prediction, DFT calculations, molecular dynamics simulations, machine learning models), yielding a multidimensional framework for elucidating structure–property relationships in both crystalline and disordered materials. Special attention is devoted to complex environments such as multicomponent crystals, host–guest assemblies, and amorphous dispersions. Looking ahead, continued advances in ultrahigh-field instrumentation, pulse-sequence design, and NMR crystallography promise to transform SSNMR from a diagnostic into a predictive tool for supramolecular chemistry and crystal engineering, bridging microscopic interactions with macroscopic material behaviour.

Environmental pollutants, often present at low concentrations and pose a serious threat to ecological security. Traditional treatment techniques are constrained by poor selectivity, low efficiency and high susceptibility to interference from complex matrices. Molecular imprinting technology (MIT), characterized by exceptional selectivity in specific recognition and a simplified yet precise fabrication process, is increasingly emerging as a promising tool in the environment monitoring field. By integrating with various catalytic factors, molecularly imprinted catalysts (MICs) offer an effective solution to this challenge. This review systematically summarizes the underlying principles of photocatalysis, electrocatalysis, and enzyme-mimicking catalysis in MICs. Furthermore, it highlights the recent advances in various forms of MICs and their practical applications in pollutant degradation for the first time. The potential toxicity and environmental impact of MICs materials and their degradation products are also critically evaluated. This work aims to inspire novel applications of MIT in catalysis, offer methodological insights into the effective removal of persistent pollutants, and provide a forward-looking perspective to encourage further exploration by emerging researchers in this interdisciplinary field.

Reactive oxygen species (ROS), reactive nitrogen species (RNS), and reactive sulfur species (RSS), when overproduced during sustained inflammatory responses, cause oxidative stress and contribute to various acute and chronic diseases. Monitoring these molecules is crucial for understanding pathological mechanisms and evaluating therapeutic effects. This review provides a systematic comparison of fluorescent, bioluminescent, and chemiluminescent probes for in vivo imaging of ROS, RNS and RSS in inflammatory diseases. Over the past decade, each modality has developed distinct advantages: fluorescence offers high-resolution real-time visualization, bioluminescence enables deep-tissue imaging with ultra-low background, and chemiluminescence allows direct, excitation-free detection of redox activity. To clarify this landscape, we employ a “building-block” logic to dissect the design principles and evolutionary trajectories of these probes. Focusing on inflammation and related disease models, we highlight the transformative potential of bioluminescent and chemiluminescent probes for real-time monitoring of oxidative stress. This work provides a structured guide for selecting and innovating optical probes in redox biology.

Recent technological advancements, rising energy crises, and environmental pollution have prompted the development and synthesis of innovative materials for efficient energy conversion and water purification in order to fulfil society's clean energy and water needs. A variety of pollutants have grown more persistent in aquatic environments. The inappropriate use of dyes and antibiotics, as well as their inadequate digestion in organisms, results in their discharge into aquatic habitats, which has harmed human health. Therefore, effective removal of textiles and pharmaceuticals, especially dyes and antibiotics, from wastewater and polluted water bodies is of significant interest to research communities across the world. Besides, the depletion of fossil fuels increases the demand for renewable energy sources. Since solar energy is the most abundant and endless energy source, it provides an environmentally friendly alternative to fossil fuels. Metal-organic frameworks (MOFs), which are porous crystalline hybrid materials formed by the linkage of metal centers (clusters) and organic linkers (organic ligands), have been identified as a highly active research domain for more than a decade due to their wide range of applications as photocatalytic and photovoltaic. In the present research domain, the research community has been drawn to emerging MOFs by their distinctive properties, which include a large surface area, controllable morphologies, tunable porosities, layer-by-layer design, high-quality crystalline products, outstanding inorganic-organic nature, and incredible diversity in functionalities. In this review, the latest developments in the use of MOFs and their derivatives in a variety of solar cell technologies, such as dye-sensitized, perovskite, and organic solar cells, are methodically described. These MOF-based photovoltaic systems have shown remarkable potential for enhancing sunlight-to-electricity conversion efficiency and improving stability. In addition, the utilization of MOFs and their derivatives as photocatalysts is a highly effective approach for breaking down dye and antibiotic residues in water. Key improvements and modifications, such as stronger interfacial contact, enhanced light harvesting, and improved charge separation, have been emphasized to develop potent photocatalysts that significantly enhance the removal of dyes and antibiotics. The environmental factors influencing photocatalytic degradation activity, such as photocatalyst concentration, pollutant concentration, solution pH, light intensity, reaction temperature, Fenton reagent, and scavengers, were thoroughly discussed, assisting in the design of an ideal photoreactor with high photocatalytic efficiency and a cost-effective process. Furthermore, the remaining significant challenges in the aforementioned domains are addressed, and potential future research endeavours in the development of MOFs are also outlined.

Covalent organic frameworks (COFs), characterized by high specific surface area, tunable pore structures, and excellent stability, provide an ideal platform for developing high-performance ratiometric fluorescence sensors. By measuring the intensity ratio of two emission signals, these sensors offer built-in self-calibration, overcoming the limitations of single-signal probes affected by environmental interference, and thus improving sensitivity, selectivity, and reliability in detecting trace analytes in complex samples. This review systematically outlines construction strategies for dual-emission COF-based ratiometric sensors, such as intrinsic backbone dual-emission, doping-induced dual-emission, and hybrid/heterostructure-induced dual-emission. For each approach, advantages, limitations, and development directions are discussed. Key structural factors (e.g. topology, π–π stacking, donor–acceptor motifs, pore environment, and crystallinity) and their roles in integrating luminescent units are discussed to explain how they collectively influence dual-emission performance and stability. Common construction challenges and corresponding mitigation strategies are also summarized to enhance sensor reliability and efficiency. The review further elaborates on relevant sensing mechanisms, including excited-state intramolecular proton transfer (ESIPT) and Förster resonance energy transfer (FRET), as well as summarizes the interrelationships of construction strategy-response mode-sensing mechanism. Performance advantages and recent applications in environmental monitoring, food safety, and biomedical analysis are highlighted. Despite their promise, practical use of these sensors still faces challenges in signal controllability and environmental adaptability. Based on current limitations, this review suggests future directions: precise control and mechanistic study of dual-emission behavior, enhancing signal reliability in real samples and enabling device integration, and data-driven material design for performance optimization. Through collaborative advances, dual-emission COF-based sensors are expected to evolve into versatile detection platforms for environmental, clinical, and food safety applications, promoting the practical adoption of next-generation sensing technologies.

N-Heterocyclic carbenes (NHCs) have become cornerstone ligands in modern coordination and main-group chemistry, yet their interactions with metal and non-metal fluorides have long remained underexplored because many fluorides are poorly soluble and often difficult to handle. This review surveys the synthesis, structures, and reactivity of all structurally characterized NHC complexes and adducts containing the NHC-M-F fragment reported from the advent of isolable NHCs (1991) through mid-2025. Across 33 elements spanning the s-, p-, d-, and f-blocks, we compile 458 reported compounds, including 277 crystallographically authenticated species, and organize the field by element group and oxidation state. Emphasis is placed on practical synthetic entry points: direct coordination to soluble fluoride sources, transmetalation and synthon strategies, dehydrofluorination routes from fluoride salts, fluorination of pre-formed halide, hydride, or organo precursors, and redox-driven fluoride formation. We highlight how ligand sterics and electronics (including CAAC and related carbenes) govern stability and speciation. Comparative analysis of NHC–M and M–F metrics, typical geometries, and 19F NMR ranges reveals periodic trends and recurring structural motifs, providing a unified reference framework for designing new NHC-stabilized fluoride compounds and leveraging their distinctive reactivity.

This review addresses the growing demand for sustainable energy technologies by exploring the rapid advancements in organic dyes for aqueous-based electrochemical energy storage (AEES). By examining their functional groups, structural properties, and solvation behavior, we explore the mechanisms that govern their electrochemical behavior in aqueous environments. Organic dyes enhance interfacial charge transport via proton-electron coupled exchange. Their electrochromic behavior allows for versatile applications in AEES systems. The review systematically categorizes prominent dyes- including anthraquinone, azo, nitro, triphenylmethane, and heterocyclic compounds and highlights their redox mechanisms and electrochemical properties. Advanced analytical techniques, such as UV–Vis, Raman, FTIR, and NMR spectroscopy, provide critical insights into structure-function relationships. Investigations into aqueous solubility, ion coordination effects, and interfacial interactions emphasize the multifunctional potential of these materials. Challenges, including the irreversible transformation and shuttling effect, are addressed in dye-containing electrolytes. Additionally, the incorporation of organic dyes with conductive polymers and carbon-based additives, such as graphene and carbon nanotubes, improves charge storage and electrochemical stability.

Diamond-like (DL) compounds constitute a pivotal class of materials for advanced optoelectronic applications, particularly as infrared (IR) nonlinear optical (NLO) crystals, owing to their intrinsically high proportion of non-centrosymmetric structures and oriented tetrahedral units that synergistically enhance second-order NLO responses. Over the past decades, more than 300 DL compounds have been rationally designed and synthesized, with over 90 demonstrating significant NLO activity. However, performance-driven DL structural design remains highly challenging in this field. To advance the targeted design of high-performance IR NLO materials, this review provides a systematic and updated summary of DL IR NLO compounds, with a particular emphasis on emerging and promising alkaline earth metal tetrahedral and mixed anionic NLO-active tetrahedral units, chemical and structural diversity, structural evolution, and property modifications in DL chalcogenide, pnictide, and halide systems. Finally, future opportunities and challenges in DL functional material discovery are discussed, with the aim of providing a clear chemical perspective to stimulate the discovery of new DL IR NLO materials with desired properties.

Heavy metals pose a serious threat to global water systems due to their toxicity, persistence, and strong bioaccumulative potential in ecosystems and humans. Among various remediation strategies, adsorption is regarded one of the most effective and versatile approaches. Biochar (BC) has gained significant attention as a sustainable and low-cost adsorbent owing to its simple preparation, tunable porosity, high surface area, and intrinsic functional groups. However, pristine BC often exhibits limited adsorption efficiency toward diverse metal ions, necessitating targeted engineering and surface modification. To address this, two modification approaches, namely metal-based nano-architected BC (NA-BC) and surface-functionalized BC (f-BC), have emerged as leading platforms. NA-BCs are synthesized from either single metals (e.g., oxides, hydroxides, and metal-organic frameworks) or multi-metal systems (e.g., layered double hydroxides, spinel oxides), with magnesium, manganese, calcium, aluminum, zinc, and iron commonly used as precursors for their low toxicity, cost-effectiveness, and chemical versatility. Meanwhile, surface functionalization introduces hydroxyl, amino, sulfonic, thiol, carboxylic, and phosphate groups via inorganic or organic modifications, yielding f-BCs and f-NA-BCs with tunable porosity, enriched surface functionalities, and enhanced stability. These features collectively improve adsorption capacity, selectivity, and reusability. The heavy metal removal by BC composites involves physisorption and chemisorption, including pore diffusion, electrostatic attraction, chelation/coordination, ion exchange, precipitation, and redox reactions, which can be validated through XRD, FTIR, XPS, and DFT analyses. Looking ahead, advancing scalability, environmental safety, and machine-learning-guided material design will be crucial for developing next-generation engineered BCs capable of practical implementation in fixed-bed filters in disaster-affected zones and industrial wastewater treatment.
重金属由于其毒性、持久性以及在生态系统和人类中具有很强的生物蓄积性，对全球水系统构成严重威胁。在各种修复策略中，吸附被认为是最有效和通用的方法之一。生物炭（BC）由于其制备简单、孔隙度可调、比表面积大、固有官能团多等优点，作为一种可持续的低成本吸附剂受到了广泛关注。然而，原始BC对多种金属离子的吸附效率有限，需要有针对性的工程和表面改性。为了解决这个问题，两种改性方法，即金属基纳米结构BC （NA-BC）和表面功能化BC (f-BC)，已经成为领先的平台。na - bc由单一金属（如氧化物、氢氧化物和金属有机框架）或多金属体系（如层状双氢氧化物、尖晶石氧化物）合成，镁、锰、钙、铝、锌和铁通常用作前体，因为它们毒性低、成本效益好、化学用途广泛。同时，表面功能化通过无机或有机修饰引入羟基、氨基、磺酸基、巯基、羧基和磷酸基，生成孔隙度可调的f- bc和f- na - bc，表面功能丰富，稳定性增强。这些特性共同提高了吸附能力、选择性和可重用性。BC复合材料对重金属的去除涉及物理吸附和化学吸附，包括孔隙扩散、静电吸引、螯合/配位、离子交换、沉淀和氧化还原反应，可以通过XRD、FTIR、XPS和DFT分析进行验证。展望未来，推进可扩展性、环境安全性和机器学习指导的材料设计对于开发下一代工程bc至关重要，这些bc能够在受灾地区的固定床过滤器和工业废水处理中实际实施。
