Bithienyl-1,3-benzothiazole derivatives were synthesised by reacting various 5-formyl-5′-alkoxy- or 5-formyl-5′-N,N-dialkylamino-2,2′-bithiophenes with ortho-aminobenzenethiol in good to excellent yields. Evaluation of the fluorescence properties of these compounds was carried out. They show strong fluorescence in the 450–600 nm region, as well as high quantum yields and large Stokes’ shifts.
通过使各种5-甲酰基-5'-烷氧基-或5-甲酰基-5'- N,N-二烷基氨基-2,2'-联噻吩与邻-氨基苯硫醇良好或优异地反应来合成Bithienyl-1,3-苯并噻唑衍生物产量。评估这些化合物的荧光性质。它们在450-600 nm区域显示强荧光,并具有高量子产率和较大的斯托克斯位移。
