Photochromism material of new unsymmetrical isomeric diarylethenes bearing a thiophene and pyridine unit

摘要

A new photochromic diarylethene compound, 1-(2,5-dimethyl-3-thiophene)-2-[5-(4-pyridine)-2-methyl-3-thienyl]perfluorocyclopentene(1a) was synthesized. its photochromic and fluorescent properties have been investigated in detail. The results of the research showed that it has shown good photochromic behavior and fluorescence switch in solution and PMMA film. Finally, photo-mode rewritable optical storage using 1b was performed. The images demonstrated that the compound can be used as optical storage material.
