Here, the as-synthesized bis-triarylboron compounds doped in poly(methyl methacrylate (PMMA) films show highly matched UV absorption and high FLQY (up to 0.65), attributed to intramolecular space conjugation effect.

A hypoxia-responsive nanomedicine NM-CB/Ce6 with prominent biocompatibility to co-deliver chlorambucil (CB) and chlorin e6 (Ce6) was prepared using a self-immolative PEGylated dendritic drug conjugate block-dendritic-polymer. Upon 650 nm near-infrared light (NIR) irradiation, the encapsulated Ce6 consume oxygen to generate single oxygen (1O2) for photodynamic therapy (PDT). Under the NIR-induced aggravated hypoxia, this nanomedicine can facilitate cellular internalization owing to hypoxia-responsive dePEGylation, and further disintegrate inside HepG2 cells to rapidly release activated CB for chemotherapy (CT).

Herein, we demonstrate that the thermal back reactivity of diarylbenzene photoswitches depends on the degree of twisting of the aryl groups. Density functional theory calculations reveal that the π-conjugation length in the transition state is the key to determining the activation free energy.

All-solid-state lithium metal batteries (ASSLMBs) have garnered significant attention due to their potential for high energy densities and enhanced safety. Solid-state electrolytes (SSEs) are critical components in ASSLMBs, with their ionic conductivity and interfacial compatibility directly influencing battery performance. However, current SSEs often exhibit lower ionic conductivity and higher interfacial resistance compared to liquid electrolytes. To address these challenges, high-entropy strategies have emerged as a promising approach to enhance structural disorder and stability in SSEs. This review provides a comprehensive overview of high-entropy strategies applied to SSEs, including inorganic, polymer, and composite SSEs. We elucidate the fundamental concepts of high entropy and its four core effects (high-entropy effect, lattice distortion effect, sluggish-diffusion effect, and cocktail effect) and discuss their impact on SSEs performance. Recent progress in applying high-entropy strategies to different types of SSEs is summarized, highlighting structural optimization and performance enhancement. Challenges and future directions for the development of high-entropy SSEs are also presented. The insights provided in this review aim to guide the rational design of high-performance SSEs for next-generation energy storage system.

Herein, we computationally predict two FCC gold nanoclusters, Au212(SR)60 and Au224(SR)72, featuring octahedral Au6 cores at the 200-atom scale. Au224(SR)72 exhibits superior structural stability compared to Au212(SR)60. Spectroscopic and electronic analyses reveal that FCC-structured Au224(SR)72 retains molecular-state characteristics, proving FCC configuration alone insufficient to impart metallic properties in large RS-AuNCs. Crucially, comparative studies between twinned-FCC Au191(SR)66 and pure-FCC Au224(SR)72 demonstrate that twinned configurations significantly lower the critical atom threshold for metallic behavior emergence. This work elucidates how core packing modes regulate electronic properties in RS-AuNCs, providing critical design principles for tailoring their optoelectronic characteristics.

In this work we report Cs2PdX6 (X = Cl, Br) photoanodes for photoelectrochemical solar water oxidation. These materials show panchromatic absorption with exceptional stability in ambient air, water, and extreme pH conditions. Cs2PdBr6 demonstrated a photocurrent of 1 mA cm-2, the highest reported for any vacancy-ordered halide perovskite in direct solar water oxidation. Apart from the parent materials, the anion exchange from chloride to bromide was carried out to create core-shell heterostructures.

Here, we report a selective crystallization strategy to efficiently separate Th(IV) from Ln(III), yielding a new Th-oxo cluster (Th-pca). REEs such as Eu(III) and Yb(III) remain in solution, affording exceptional separation factors of 203,935 (Th/Eu) and 111,229 (Th/Yb). Th-pca also displays photothermal properties, rendering it as a rare actinide-based material with this functionality.
