Covalent Organic Frameworks: Dual‐Function Fluorescent Covalent Organic Frameworks: HCl Sensing and Photocatalytic H2 Evolution from Water(Advanced Optical Materials 18/2020)

Ultrastable luminescent covalent organic frameworks (COFs) having different degrees of conjugation are successfully developed by Ho-Hsiu Chou, Shiao-Wei Kuo and co-workers (see article number 2000641) and present ultrastable thermal stability, excellent crystallinity, and strong fluorescence emissions in various solvents with solvatochromic behavior. The COFs exhibit a rapid and sensitive response to HCl exposure and a high efficiency for photocatalytic evolution of H2 from water in the absence of a noble metal.
