π共轭聚合物在非晶态碳片、玻璃板等基底表面的垂直、平行排列是近年来研究的热点。最近的研究表明：(1)具有96%区域规则性的区域规则性（HT）聚（3-己基噻吩- 2,5 -二基）（P3HexTh）在自旋涂覆时更倾向于具有面向SiO2/Si衬底表面的己基的排列结构；(2)由此获得的HT-P3HexTh薄膜比自旋涂覆的区域随机P3HexTh薄膜产生更大的载子迁移率。高迁移率对于构建具有优异性能的电子和光学聚合物器件非常重要，HT-P3HexTh的这种排列可能与最近报道的HT-P3HexTh的超导性有关。在我们之前关于HT-P3HexTh电化学沉积98.5%区域规则性的研究中，我们也注意到HT-P3HexTh分子的类似排列，在各种底物上具有更高的取向程度。
The perpendicular1, 2 and parallel2, 3 alignment of π-conjugated polymers on the surfaces of substrates such as amorphous carbon sheets and glass plates has been a subject of recent interest. It has been recently demonstrated (1) that regioregular head-to-tail (HT) poly (3-hexylthiophene-2, 5-diyl)(P3HexTh) with 96% regioregularity prefers an aligned structure with the hexyl group oriented toward the surface of a SiO2/Si substrate when spin-coated and (2) that the HT-P3HexTh film thus obtained yields a much larger carrier mobility than a spin-coated film of regiorandom P3HexTh. 4 The higher mobility is important for the construction of electronic and optical polymer devices with excellent performance, and such alignment of HT-P3HexTh might be related to the very recently reported superconductivity of HT-P3HexTh. 5 In our previous studies6, 7 on the electrochemical deposition of HT-P3HexTh with 98.5% regioregularity, we also noted a similar alignment of HT-P3HexTh molecules, with a higher degree of orientation on various substrates.
