Synthesis and Application of 1-2-methyl-5-phenyl-3-thiophene-2-2-methyl-5-phenyl-(4-vinyl)-3-thiophene perfluorocyclopentene

摘要

A new unsymmetrical photochromic diarylethene 1-(2-methyl-5-phenyl-3-thiophene)-2-[2-methyl-5-phenyl-(4-vinyl)-3-thiophene]perfluorocyclopent ene (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 blue upon irradiation with 297 nm UV light, in which absorption maxima were observed at 596 nm in acetonitrile.
