This article discusses the Egap of polythiophene that with electron-drawing groups and electron- withdrawing groups. The electron-drawing groups and electron-withdrawing groups affect onπ-electron conjugated structure and Egap. The theoretical method are ZINDO//AM1 ,ZINDO//PM3 and ab-initio TD-DFT。In electron-drawing groups substituted poly-thiophene,they are alkylgroups,OCH3,OH,NH2,PITN,PEDOT,SCH3, and poly(2-decylthieno[3,4-β]thiophene),all of the polythiophene with electron-drawing groups that the Egap are lower than polythiophene and the order of Egap is alkyl-PTH>PEDOT>SCH3-PTH>poly(2-decylthieno[3,4-β]thiophene)>OH-PTH>NH2-PTH>OCH3-PTH>PITN。Viewed in electron-withdrawing groups substituted polythiophene aspect,they are CF3、Cl、NO2、CHO and COOH,all of the electron-withdrawing groups substituted polythiophene that the Egap are higher than polythiophene and the order of Egap is Cl-PTH>NO2-PTH>CF3-PTH>COOH-PTH>CHO-PTH。 王伯昌 2004 學位論文 ; thesis 107 zh-TW
