The past ten years have evidenced the rapid development of bipyridinium-based coordination polymers, however, design and synthesis photo-switchable luminescent materials with a non-destructive readout capability based on bipyridinium ligands are still at primary stage. In this work, two new polymers bipyridinium-functionalized m-benzenedicarboxyl ligand were synthesized for purpose. By using anions different geometries, molecular linkage packing structure been adjusted, thus allow title...

The self-assembly of a photoactive 1,1′-bis(4-carboxybenzyl)-4,4′-bipyridinium ligand with cadmium chloride in the presence strong electron-donating oxalate anion has successfully afforded photochromic coordination polymer, which shows high sensitivity not only to ultraviolet-visible radiation but also X-rays.

This review paper provides an overview of recent development in detectors based on perovskite single crystals and the challenges they pose.

A novel thin-film composite polyamide membrane for nanofiltration is prepared, and the addition of sodium <italic>N</italic>-cyclohexylsulfamate found to have a significant influence on its performance.

Interests in chromic materials are rapidly increasing for their potential applications as smart responsive materials. However, the majority of existing ones triggered by merely one or two outer stimuli and few multi-stimuli examples still suffer from confining functioning state such solution polymer. To address these challenges, a new generation is being intensively pursued. In this article, we report neoteric supramolecular solid material assembling Co(II) ion with...

Two non-centrosymmetric alkaline-earth metal borates, Ca2[B5O8(OH)]2[B(OH)3]·H2O (1) and Ba2[B6O9(OH)2][B3O3(OH)4]·(OH)·4H2O (2), have been synthesized under solvothermal conditions. Both of them exhibit layered structures constructed from two fundamental building blocks (FBBs), respectively. 1 features porous double-layers made by the acentric single A-layer B-layer in a face-to-face arrangement. Ca-O layers gather B-O together resulting chiral structure 1. Compound 2 contains different...

This work demonstrates Cu–NHC (NHC = N-heterocyclic carbene) catalyzed alkynylation of aryl thianthrenium salts via thiazol-2-ylidene ligands, achieving a Pd-free Sonogashira coupling with broad substrate compatibility and functional group tolerance. Late-stage pharmaceutical rare alkynylative C–H functionalization/ring-opening pathways are enabled. Thiazol-2-ylidenes, featuring "half-umbrella"-shaped geometry, exhibit superior catalytic performance over traditional imidazol-2-ylidenes,...
