Synthesis of arylenebis(2-aminothiophene-3-carbonitriles) by the Gewald reaction was developed. The structures of the synthesized monomers were established by IR and NMR spectroscopy, mass spectrometry, and microanalysis. Polycondensation of these monomers with diacetylferrocene gave azomethine-bridged polythiopheneferrocenes.

用于合成新型聚噻吩二茂铁的含噻吩单体

开发了通过 Gewald 反应合成亚芳基双（2-氨基噻吩-3-腈）的方法。通过红外光谱和核磁共振光谱、质谱和微量分析确定了合成单体的结构。这些单体与二乙酰二茂铁的缩聚得到偶氮甲碱桥连的聚噻吩二茂铁。
