Abstract

A new type photochromic diarylethene, 1-(2-ethylbenzo[b]thiophen-3-yl)-2- (2-methylphenyl)perfluorocyclopentene (1o), was synthesized, and its photochromic and fluorescent properties were investigated. This compound exhibited reversible photochromism and notable fluorescence photoswitches both in solution and in PMMA films. In addition, the fluorescence spectra of diarylethene 1o evidently depended on the concentration in hexane. Using diarylethene 1c/PMMA film as recording medium, optical recording was carried out successfully.
