Synthesis and Properties of a New Diarylethene Bearing Isoxazole Moieties

Abstract:

A new unsymmetrical photochromic diarylethene bearing an isoxazole moiety was developed, and its properties, including photochromism, photochromic reaction kinetics, and fluorescence properties were investigated systematically. The compound exhibited remarkable photochromism and functioned as a fluorescent photoswitch both in solution and in PMMA films. The results illustrated that the cyclization processes of diarylethene 1 belong to the zeroth order reaction when open-ring isomers changed to closed-ring isomers and the cycloreversion process belong to the first order reaction. Inaddition, using this diarylethene 1c as optical storage was performed successfully.
