Paper Abstract

Photochromic symmetrical diarylethenes derivatives 1a-4a bearing different long alkyl chains at 2-position of thiophene rings have been synthesized and their photochromism and kinetics of the photochromic cyclization/cycloreversion both in hexane and in PMMA film were investigated. The results showed that the cyclization/cycloreversion process of these compounds were determined to be the zeroth/first order reaction, and the different long alkyl chains effects on kinetics according to the data of reaction rates both in hexane and PMMA film.
