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 photochromic 1,2-dithienylethene derivative (1) with a 2,2,5,5-tetrafluoro-2,5-dihydro- furan bridge unit was designed and synthesized. The key intermediate perfluoro-2,5-dihydrofuran (2) was prepared from cheap and readily available material hexachlorobuta-1,3-diene. The reaction of 2 with 3 -bromo-[2,2 :5 ,2 ]trithiophene (3) in the presence of n-BuLi gave the fluorinated photochromic molecule 1.
