Synthesis, Properties of a Photochromic Diarylethene Material Bearing Benzofuran and Thiazole Rings

Abstract:

A new photochromic diarylethene compound, 1-(2-methylbenzofuran)-2-[(2,4-dimethyl-5-thiazolyl] perfluorocyclopentene (1o), was synthesized, and its photochromic reactivity, fluorescent were also investigated. The results showed that this compound exhibited reversible photochromism, changing from colorless to yellow after irradiation with UV light both in solution and in PMMA amorphous film. In hexane solution, the openring isomer of the diarylethene 1 exhibited relatively strong fluorescence at 410 nm when excited at 307 nm.
