Optimizing the structure of organic solar cells (OSCs) is the key to improving their efficiency and stability. In this study, we introduce the use of highly volatile and low-cost solid additives, namely 2-phenylthiophene (PT) and 2-(3,4,5-trifluorophenyl)thiophene (TFT), to modulate the morphology optimization and enhance the efficiency of OSCs. The inclusion of PT and TFT effectively influences the aggregation behavior of D18:L8-BO during the film-forming process, increase the time of acceptor molecules, and promotes the formation of a well-organized fiber network structure. Consequently, PT and TFT-treated D18:L8-BO-based OSCs achieved power conversion efficiencies of 18.28% and 19.19%, respectively. This study provides a straightforward approach for achieving structural optimization and efficient photovoltaic performance of OCSs.

The use of N-hydroxy-2-oxopropanimidoyl chloride as a latent cyanide transfer agent is reported. This easy-to-handle, scalable, and operationally simple agent can be installed on common nucleophiles, including thiols and secondary amines, affording synthetically useful thiocyanates and cyanamides. This method complements conventional approaches that use poisonous and volatile cyanogen halides.

Recent advancements in tools using programmable RNA binding proteins and m6A-erasers enable sequence-selective and timing-controllable m6A demethylation. However, off-target effects are still concern. This study adresses the problem by reducing the RNA-binding ability of m6A-erasers. The modulated m6A-erasers achieved sequence-specific and timing-controllable m6A demethylation with minimal off-target activity.

Cations in ionic liquids (ILs) are typically derived from ammonium or phosphonium structures with long alkyl chains, and it is well established that the central atom significantly influences the properties of the resulting ILs. In this study, an arsonium-based IL, trihexylmethylarsonium bis(trifluoromethylsulfonyl)amide, was synthesized. The arsonium cation was found to contribute to lower viscosity and higher ionic conductivity, while maintaining sufficient stability compared to its phosphonium counterpart.

Van der Waals (vdW) magnets offer unique opportunities for exploring magnetism in the 2D limit. Metal-organic magnets (MOM) are of particular interest as the functionalisation of organic ligands can control their physical properties. Here, we demonstrate tuning of mechanical and magnetic function of a noncollinear vdW ferromagnet, NiCl2(btd) (btd = 2,1,3-benzothiadiazole), through creating solid-solutions with the oxygen-substituted analogue ligand 2,1,3-benzoxadiazole (bod). We synthesise solid-solutions, NiCl2(btd)1–x(bod)x , up to x = 0.33 above which we find mixtures form, primarily composed of a new 1D coordination polymer NiCl2(bod)2. Magnetometry on this series shows that bod incorporation reduces the coercivity significantly (up to 60%), without significantly altering the ordering temperatures. Our high pressure synchrotron diffraction measurements up to 0.4 GPa demonstrate that the stiffest axis is the b axis, through the Ni-N-(O/S)-N-Ni bonds, and the softest is the interlayer direction. Doping with bod fine-tunes this compressibility, softening the layers, but stiffening the interlayer axis. This demonstrates that substitution of organic ligands in vdW MOMs can be used to realise targetted magnetic and mechanical properties.

We report an iminium ion-promoted, asymmetric synthesis of cyclopropanes via an electrocatalytic, iodine-mediated ring closure. The mild, controlled electrochemical generation of electrophilic iodine species in catalytic quantities prevents organocatalyst deactivation, while also eliminating the need for halogenated reagents, thus simplifying traditional synthetic approaches.

The application of a potentiometric pH electrode in ocean acidification observation is still a challenge due to its poor sensitivity to small pH changes. Herein, a simple approach to remarkably improve the detection precision of a polymeric membrane ion-selective electrode is proposed based on the potential-modulated ion transfer mechanism. The present sensing strategy displays highly sensitive responses to small pH changes for seawater analysis with a precision of 5 µpH, which is 2 orders of magnitude lower than that of the conventional pH electrode.
