摘　　要：合成了高产率、稳定的2-氨基-5-硝基噻吩和2-氨基-3,5-二硝基噻吩,并通过重氨化,使其直接与N,N-二羟乙基苯胺偶合,得到两种偶氮型功能分子.同时合成了相应的二苯乙烯型化合物.由于这些分子的一端含有羟基活性基团,它们可作为光学活性单元挂接到聚合物中。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.
