Abstract:A photochromic bisthienylethene with pyridine(BTE-Pyridine)was designed and synthesized by Suzuki coupling reaction.The key intermediate 1,2-bis(2-chloro-3-methyl-5-thienyl)cyclopentene was synthesized with 2-chloro-5-methylthiophene and glutaric chloride via Friedel-Crafts acylation reaction,Mcmurry coupling reaction.All intermediates and the target compound were identified by 1H NMR and MS.The photochromic properties of BTE-Pyridine and its interaction with H+ and Zn2+ were also investigated by UV-Vis absorption method and fluorescent emission method.
Keywords:photochromism  bisthienylethene  pyridine  synthesis
