Synthesis and Properties of 1-(2,4-Dimethyl-5-thiazolyl)-2-(2-methyl-5-(2-methyl)-3-thienyl)perfluorocyclopentene

Abstract:

An asymmetrical photochromic diarylethene 1-(2,4-dimethyl-5-thiazolyl)-2-(2-methyl-5-(2-methyl)-3-thienyl) perfluorocyclopentene (1o) was synthesized and its photochromic properties were investigated. Upon irradiation with 297 nm UV light, 1o exhibited photochromism in solution and in PMMA film. The kinetic experiments showed that the cyclization and cycloreversion processes were zeroth and first order reaction, respectively. Moreover, diarylethene 1o also exhibited obviously fluorescence switches along with the photochromism.
