【Abstract】 It is known that the synthesis of 2 - aminothione is difficult despite its simple structure. In this work, 2 - amino - 5 - nitrothiophene and 2 - amino -3,5- dinitrothiophene were synthesized in excellent yields. After diazotization, the 2 - aminothiophene derivatives were directly reacted with N -phenyldiethanolamine to afford two electron push - pull compounds. A similar styryl compound was also prepared. All these chromophore molecules have further polycondensable hydroxyl groups at one end of the molecules. These compounds are currently interesting due to their potential in making highly sensitive nonlinear optical polymeric materials.更多还原
