A robust MOF with diethylammonium cations in its pores, enhances pore partitioning and modifies the environment, enabling selective and dense SO packing through hydrogen bonds. It achieves a reversible SO uptake with a high adsorption enthalpy and record IAST selectivity of 1182 for SO/CO at 298 K and 1 bar.

The refinement of dynamic molecular mechanisms regulating mRNA release kinetics represents a critical frontier in advancing the synthetic mRNA delivery systems. This study details the synthesis of an intriguing ROS-responsive cationic block copolymer (pM-pBD) via reversible addition-fragmentation chain transfer (RAFT) polymerization, employing biocompatible 2-methacryloyloxyethyl phosphorylcholine (MPC) and charge-reversible (2-acryloyl)ethyl(boronic acid benzyl)diethylammonium bromide (BD) as monomeric precursors. The synthesized copolymer facilitates electrostatic-driven self-assembly with anionic mRNA.

Due to the band offset, there is significant interfacial recombination between the tin-based perovskite and C, which exhibits excellent electron transport capability. Here, we introduce a novel strategy leveraging surface self-passivation through controlled thermal decomposition to reduce the level of interfacial recombination substantially. By carefully tuning the annealing temperature (70 vs 100 °C) and organic cation composition (diethylammonium (DEA) vs methylamine (MA)), we achieve selective surface restructuring and SnI formation, effectively suppressing interfacial recombination at the perovskite/C interface.

The reaction between molybdenum(ii) acetate and 5-aminoisophthalic acid (HIso-NH) afforded [MoO(μ-O)(Iso-NH)], a novel molybdenum(v) metal-organic polyhedron (MOP) with a triangular antiprismatic shape stabilized by intramolecular N-H⋯O hydrogen bonds. The synthesis conditions, particularly the choice of solvent and reaction time, led to the precipitation of the Mo(v)-MOP in five distinct crystalline forms. These forms vary in their packing arrangements, co-crystallized solvent molecules, and counter-cations, with three phases containing dimethylammonium (dma) and the other two containing diethylammonium (dea).

In this work, we have reviewed non-covalent interactions in technetium hexahalide compounds and obtained eight new compounds of the CatTcHal type, where Cat = dimethylammonium, tetramethylammonium, caffeinium, benzothiazolium, nicotinamidium, and pyrazolium, and Hal = Cl, Br. SCXRD studies were carried out for new compounds. In some compounds, halide anions and/or crystallization water were present.
