Synthesis and Properties of a New Photochromic Material Based on Isoxazole Unit for Optical Storage Recording

Article Preview

Abstract:

A novel photochromic diarylethene compound containing isoxazole unit, 1-(3,5-dimethyl-4-isoxazolyl)-2-[2-methyl-5-hydroxymethyl-3-thienyl]perfluoroyclopentene have been synthesized. Its photochromic, fluorescent and optical storage properties were investigated. The compound exhibited remarkable photochromism both in solution and in PMMA film. In addition, the open-ring isomer of the diarylethene 1a exhibited relatively clear fluorescent switches in hexane solution and PMMA film when excited at 300 nm. This new photochromic system also exhibited remarkable optical storage character
