摘要

An unsymmertrical diarylethene compound 1-(2-methyl-1-benzofuran-3-yl)-2-[2-methyl-1-benzothiophene-3-yl] Perfluorocyclopentene was synthesized and its photochromism was investigated, the results showed that this compound exhibited reversible photochromism, inducing cyclization and cycloreversion reactions upon alternating irradiation with UV and visible light both in solution and in PMMA film. When irradiated 297 nm UV light, the maximum absorption was observed at 498 nm and 509 nm in hexane solution and in PMMA film, respectively.
