It is known that the synthesis of 2-aminothione is fifficult 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-phenuldiethanolamine to afford two electron push0pull compounds. A similar styryl compound wa also prepared. All these chromophore molecules hve 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 polymieric materials.
