Synthesis of a New Photochromic Diarylethene Based on Isoxazol and Thiophene Ring for Optical Storage

摘要

A new unsymmetrical diarylethene derivative 1-(2,4-dimethyl-isoxazol-3-yl)-2-(2-methyl-5-formyl-3-thienyl) perfluoroyclopentene (1a) was synthesized. Its photochromic and fluorescent properties were investigated, respectively. The results showed that this diarylethene exhibited reversible photochromism, the ring-closed isomer absorption maxima were observed at 519 nm and 527 nm in hexane and PMMA film, respectively. In hexane solution, diarylethene 1 showed good fluorecence switching characters with 309 nm light excited.
