Abstract

Matched with 3,5-bis(pyridine-2-yl)-1,2,4-triazole (2-bpt), a new electron donor-acceptor-based chlorobismuthate(III) hybrid, [2-bpt][BiCl(HO)]·5HO was prepared solvothermally and characterized. The title compound (hydrated form) and its dehydrated form exhibit photo- and thermo-induced intermolecular electron transfer (ET), which correspond to dual ET photo/thermochromism for hydrated form, charge transfer thermochromism during dehydration, and simultaneously photoluminescent responses, respectively.

摘要

与3,5-双（吡啶-2-基）-1,2,4-三唑（2-bpt）相匹配，通过溶剂热法制备并表征了一种基于新型电子供体-受体的氯铋酸盐（III）杂化物[2-bpt][BiCl(HO)]·5HO。标题化合物（水合形式）及其脱水形式表现出光致和热致分子间电子转移（ET），分别对应于水合形式的双ET光/热致变色、脱水过程中的电荷转移热致变色以及同时的光致发光响应。
