利用具有不同表面能的聚二甲基硅氧烷印章制备的有机场效应晶体管(OFET)研究了区域规则聚(3-己基噻吩基)(P3HT)自组织聚合物半导体中空气介导的分子有序化。场效应管测量表明，空气界面处的P3HT薄膜微结构与衬底界面处的P3HT薄膜微结构有很大的不同，并且前者的电荷传输效率较高。这些结果表明，空气介导的自组织在P3HT/空气界面形成高度有序的微结构几乎不受衬底介导的P3HT薄膜另一界面分子有序化的影响。(C)2011年美国物理研究所。[DOI：10.1063/1.3553481]
Air-mediated molecular ordering in the self-organized polymer semiconductor of regioregular poly(3-hexylthiophene) (P3HT) is investigated using organic field-effect transistors (OFETs) fabricated by microcontact printing using poly(dimethylsiloxane) stamps having varying surface energy. OFET measurements reveal a large difference between the P3HT thin film microstructure at the interface with air and that at the interface with the substrate and efficient charge transport through the former. These results indicate that the formation of a highly ordered microstructure at the P3HT/air interface through air-mediated self-organization is little affected by substrate-mediated molecular ordering at the other interface of the P3HT film.
