Photochromism and Fluorescent of a Novel Diarylethene Bearing Methylpyridine Group

Abstract:

A new unsymmetrical photochromic diarylethene compound, 1-(2-methyl-3-benzofuranyl)-2-[2-methyl-5-(2-methyl-6-pyridyl)-3-thienyl] perfluorocyclopentene (1o), was synthesized and its photochemical, fluorescence properties were investigated systematically both in solution and PMMA amorphous film. The photochromic reaction kinetics results indicated that the cyclization processes of 1o belong to the zeroth order reaction and the cycloreversion process belong to the first order reaction.
