Synthesis and Properties of a New Unsymmetrical 1-(2-methyl-3-benzothienyl)-2- [2-methyl-5-(4-ethyl benzoate)-3-thienyl] perfluorocyclopentene

Abstract

A new unsymmetrical photochromic 1-(2-methyl-3-benzothienyl)-2-[2-methyl- 5-(4-ethyl benzoate)-3-thienyl]perfluorocyclopentene (1o) has been synthesized, and properties of this photochromic compound which includes fluorescence, and photochromism in both methanol solution and PMMA amorphous film have been systematically investigated. The results demonstrated that its photochromic behaviors could be modulated by UV/Vis light, changing from colorless to orchid in methanol solution. These properties are useful for rewritable optical recording or photos witches.
