采用FeCl3化学氧化聚合法合成聚{3-[(3-甲氧基-3-丙酮基)硫甲基]噻吩}的合成,用红外光谱,紫外-可见光谱和核磁共振光谱进行了结构的表征。PST具有好的溶解性和成膜性,聚合物膜的最大吸收峰位于419nm,比聚合物溶液的吸收峰红移了12nm,结果表明PST在形成薄膜时共轭程度增加。%Poly ( 3 - ( ( 3 - methoxy - 3 - oxopropy ) sulfanylmethyl ) thiophene ) (PST) was synthesized through FeC13 - oxidative polymerization and characterized by IR, 1H NMR, and UV - vis absorption spectroscopy. The PST exhibited good solubility and good film -forming abihty. The absorption peak of PST film at 419 nm, which was red - shifted 12 nm compared to PST solution, it indicated that PST exhibited more coplanar conformation.
