Synthesizes and Properties Research of 1-(1,2-dimethyl-7-azaindole-3-Yl)-2-[2-methyl-5-(4-chlorphenyl)-3-thienyl] Perfluorocyclopentene

A new photochromic diarylethene compound 1-(1,2-dimethyl-7-azaindole-3-yl)-2-[2-methyl-5-(4-chlorphenyl)-3-thienyl] perfluorocyclopentene (1o) was synthesized, which properties were systematacially studied. The results showed that its absorption maxima were observed at 583 nm in hexane and at 597 nm in a PMMA film, respectively, upon irradiation with 297 nm UV light. Moreover, the diarylethene showed a remarkable fluorescence switches upon irradiation with UV and visible light.
