【摘要】 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、¹³C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,表明聚噻吩也具有α-α′连结的结构.更多还原

【Abstract】 Thiophene oligomer（n=2—5）as model compounds for polythiophone wore synthesized and purified by sublimation,column chromatography and recrystalization.The structures of these oligomers were characterized systematically by elemental analysis,MS,UV-Vis,¹H and ¹³C NMR and IR spectroscopic methods.Comparison of results obtained with those of neutral polythiophene polymerized by electrochemical method indicates that polythiophene has the same α-α’ linked chain structure.更多还原
