A Novel Photochromic Diarylethene Based on Thiophene and Isoxazole Moieties for Optical Recording
A novel photochromic diarylethene based on isoxazole moiety was synthesized and its photochromic and fluorescent properties were also investigated. It underwent reversible cyclization and cycloreversion reactions upon alternating irradiation with UV and visible light in hexane and in PMMA film. The compound exhibited remarkable photochromism, changing from colorless to purple after irradiation with UV light. When irradiation with UV light, the fluorescence intensity declined remarkably. The results showed that the diarylethene exhibited a relatively strong fluorescence switch along with the photochromism from open-ring isomer to closed-ring isomer. Using this dithienylethene 1c as optical storage was performed successfully.
