Abstract:

A new unsymmetrical photochromic diarylethene [1-(1,2-dimethyl-cyano-3-pyrrole)-2-(2-methyl-5-thienyl-3-thienyl] perfluorocyclopentene (1o) has been synthesized, and its photochromic reactivity, fluorescent were also investigated. The results showed this compound exhibited reversible photochromism, undergoing reversible cyclization and cycloreversion reactions upon alternating irradiation with UV and visible light in solution,Diarylethene 1 changed the color from colorless to purple upon irradiation with 297 nm UV light, in which absorption maxima were observed at 585 nm in hexane.
