Synthesis and properties of a new photochromic diarylethene 1-(2-methylbenzothiophene-3-yl)-2-2-methy-5-(4-methoxyl-3-formyl) phenyl-3-thienyl perfluorocyclopentene

摘要

A novel photochromic diarylethene 1-(2-methylbenzothiophene-3-yl)-2- [2-methy-5-(4-methoxyl-3-formyl)phenyl-3-thienyl] perfluorocyclopentene (1a) has been synthesized. Its properties, including photochromic behavior and fluorescent features, have been investigated in detail. This diarylethene showed good photochromism both in solution and PMMA film and exhibited good fluorescence switching. Its also exhibits optical record property.
