Synthesis and Properties of 1-(2-methyl-3-benzothienyl)-2-[2-methyl-5-(3-trifluoromethyl)-3-thienyl]perfluorocyclopentene

Abstract:

A novel asymmetrical photochromic diarylethene 1-(2-methyl-3-benzothienyl)-2-[2-methyl-5-(3-trifluoromethyl)-3-thienyl] perfluorocyclopentene was synthesized and its photochromic and fluorescent properties were also investigated. The compound exhibited remarkable photochromism, changing from colorless to red after irradiation with UV light and the open-ring isomer of the diarylethene 1 exhibited relatively remarkable fluorescence in hexane solution. The cyclization/cycloreversion process of the compound was determined to be the zeroth/first order reaction.
