Abstract

A novel photochromic diarylethene, 1, 2-bis {2-ethyl-5-[2-(1, 3-dioxolane)]-3-thienyl} perfluorocyclopentene (BEDTP), was synthesized and its structure was determined by single- crystal X-ray diffraction analysis. Its photochromic and fluorescent properties were also investigated. The results showed that this compound exhibited reversible photochromism, changing from colorless to magenta after irradiation with UV light both in solution and in ...
