嵌段共聚物在选择性溶剂中自组装形成的胶束已经引起了广泛的关注，并在各种领域得到了广泛的应用，而基于其电子性质的应用实际上尚未被探索。本文描述了溶液可加工、低分散性、电活性、可控制长度的纤维样胶束的研究，这些胶束来自于含有结晶区域规则聚（3-己基噻吩）核和可溶解、非定形区域对称聚（3-己基噻吩）或聚苯乙烯电晕的π共轭二嵌段共聚物。隧道原子力显微镜测量表明，单个纤维表现出可观的导电性。这些纤维随后被纳入场效应晶体管的有源层。由此产生的载流子迁移率在很大程度上取决于成核块的聚合程度和纤维长度，并且与电晕组成无关。基于普通π共轭嵌段共聚物的均匀、胶体稳定的电活性纤维状胶束的使用突出了它们的巨大潜力，为器件中的电荷载流子过程提供了基本的见解，并使未来的电子应用成为可能。
Micelles formed by the self-assembly of block copolymers in selective solvents have attracted widespread attention and have uses in a wide variety of fields, whereas applications based on their electronic properties are virtually unexplored. Herein we describe studies of solution-processable, low-dispersity, electroactive fibre-like micelles of controlled length from π-conjugated diblock copolymers containing a crystalline regioregular poly(3-hexylthiophene) core and a solubilizing, amorphous regiosymmetric poly(3-hexylthiophene) or polystyrene corona. Tunnelling atomic force microscopy measurements demonstrate that the individual fibres exhibit appreciable conductivity. The fibres were subsequently incorporated as the active layer in field-effect transistors. The resulting charge carrier mobility strongly depends on both the degree of polymerization of the core-forming block and the fibre length, and is independent of corona composition. The use of uniform, colloidally stable electroactive fibre-like micelles based on common π-conjugated block copolymers highlights their significant potential to provide fundamental insight into charge carrier processes in devices, and to enable future electronic applications.
