本文合成、分离和纯化了一系列2,5-噻吩齐聚物(n=2-5),作为聚噻吩的模型化合物.首次系统报道了这类化合物的质谱、^1H、^1^3C核磁共振谱和红外光谱,以对其结构进行表征,所得结果与用电化学方法制备的中性聚噻吩的相应结果进行比较,表面聚噻也具有α-α'连结的结构.

The mol. structures of the title compounds (d.p. 2-5) as model compounds for polythiophene (I) were characterized by elemental anal., mass spectrometry, and UV, IR, and NMR spectroscopy. Comparison of results obtained with neutral I prepared electrochem. confirmed that I had the same a,a'-linked chain structure as that of the model compounds
