设计并合成了新型的以2,2,5,5-四氟-2,5-二氢呋喃桥连的1,2-二噻吩乙烯类光致变色分子1,从廉价易得的六氯丁二烯出发,经醇解、氯化、关环和氟化反应合成了关键中间体全氟2,5-二氢呋喃(2),并通过与化合物3’-溴-[2,2’:5’,2’’]三噻吩(3)的偶合反应得到含氟光致变色分子1. A novel 1,2-dithienyl-vinyl photochromic molecule 1 bridged with 2,2,5,5-tetrafluoro-2,5-dihydrofuran was designed and synthesized. From the cheap and readily available hexachlorobutadiene Starting from diene, the key intermediate, perfluorinated 2,5-dihydrofuran (2) was synthesized by alcoholysis, chlorination, ring closure and fluorination reactions, and by reaction with the compound 3’-bromo- [2,2 ’: 5 ’, 2 "] trithiophene (3) to give a fluorine-containing photochromic molecule 1.
