Synthesis and Photochromism Studies of 1-(2,4-dimethoxyl-5-pyrimidinyl)-2-[2-methyl-5-(2-methoxyphenyl)-3-thienyl]perfluorocyclopentene

Abstract:

A novel photochromic diarylethene bearing a pyrimidine unit as one aryl moiety has been synthesized. The compound exhibited remarkable photochromism, changing from colorless to violet after irradiation with UV light. When irradiated with UV light, the compound exhibited a relatively strong fluorescence switch along with the photochromism from open-ring isomer to closed-ring isomer. Using this diarylethene as optical storage was performed successfully.
