Synthesis and Application of 1-(2,5-dimethyl-3-thiazolyl)-2-[2-methyl-5-phenyl-(4-vinyl)-3-thiophene]perfluorocyclopentene

Abstract:

A new unsymmetrical photochromic diarylethene 1-(2,5-dimethyl-3-thiazolyl)-2-[2-methyl-5-phenyl-(4-vinyl)-3-thiophene] perfluorocyclopentene (1o) was designed and constructed successfully. And its photochromic reactivity, HPLC, kinetics were also investigated systematically. Upon alternating irradiation with UV and visible light in solution, this compound exhibited reversible photochromism, undergoing reversible cyclization and cycloreversion reactions. Diarylethene 1 changed the color from colorless to orange, in which absorption maxima were observed at 596 nm in acetonitrile. What is more, the photoconversion ratio of 1 is 37%.
