Paper Abstract

An unsymmetrical diarylethene derivative 1-(2,5-dimethyl-3-thienyl)-2-[2-methyl-5-(4-hydroxylphenyl)-3- thienyl]hexafluorocyclopentene (1a) was synthesized. At the same time, its photochromic properties and fluorescence switch were investigated in detail. The results showed that this compound exhibited reversible photochromism, undergoing reversible cyclization and cycloreversion reactions upon alternating irradiation with UV and visible light both in solution and in PMMA film, and its absorption maxima were observed at 547 nm in hexane and at 554 nm in PMMA amorphous film, respectively, upon irradiation with 297 nm UV light. The fluorescence intensity of diarylethene decreased dramatically along with the photochromism from open-ring isomer to closed-ring isomer upon irradiation with 297 nm UV light in hexane. In hexane the open-ring isomer of the diarylethene 1 exhibited relatively fluorescence at 507 nm when excited at 375 nm. This new photochromic compound also exhibited remarkable optical storage character.
