The synthesis of a copolymer derived from poly(3-hexylthiophene), one of the monomers bearing an aniline group, is described. Like the homopolymer, this copolymer is able to functionalize carbon nanotubes by π-stacking of the thiophene units onto the hexagonal network of the nanotubes. It can as well be covalently attached onto carbon nanotube walls without the need for an intermediate chemical step. While the dispersion of non-covalent nanohybrids in THF is stable for only a few hours, one of the covalent nanohybrids is stable for weeks, showing the efficiency of the functionalization. The comparison between the spectroscopic characterization of both covalent and non-covalent systems shows that the copolymer organizes differently at the interface with the nanotubes in each case, in agreement with the effectiveness of the addition reaction.

用于碳纳米管单步共价官能化的苯胺附加P3HT的设计与合成

描述了衍生自聚（3-己基噻吩）（一种带有苯胺基的单体之一）的共聚物的合成。类似于均聚物，该共聚物能够通过将噻吩单元π堆叠到纳米管的六边形网络上来官能化碳纳米管。它也可以共价连接到碳纳米管壁上，而无需中间的化学步骤。虽然非共价纳米杂化物在THF中的分散仅稳定几个小时，但一种共价纳米杂化物却稳定了数周，显示出功能化的效率。共价和非共价体系的光谱表征之间的比较表明，在每种情况下，与加成反应的有效性一致，共聚物在与纳米管的界面处的组织方式不同。
