Abstract

Reported herein is the first time mechanochromic materials based on sole enol-form emission of 2-(2′-hydroxyphenyl)azoles containing one triphenylamine (TPA). Three different single crystals were obtained and represent pristine, intermediate, and ground states, respectively. The 2-(2′-hydroxyphenyl)azoles containing two TPA exhibit balanced dual-emission and could be used in multi-channel imaging, and selectivity accumulated in mitochondria of living cells. In addition, we developed the first example of excited state intramolecular proton transfer (ESIPT) materials with sole enol-form emission and balanced dual-emission to detect chemical warfare agents (CWAs) mimic diethyl chlorophosphate (DCP) with good selectivity, highly sensitive, and fast responsive.

期刊介绍： Science China Materials (SCM) is a globally peer-reviewed journal that covers all facets of materials science. It is supervised by the Chinese Academy of Sciences and co-sponsored by the Chinese Academy of Sciences and the National Natural Science Foundation of China. The journal is jointly published monthly in both printed and electronic forms by Science China Press and Springer. The aim of SCM is to encourage communication of high-quality, innovative research results at the cutting-edge interface of materials science with chemistry, physics, biology, and engineering. It focuses on breakthroughs from around the world and aims to become a world-leading academic journal for materials science.
