Data from: Convenient fabrication of conjugated polymer semiconductor nanotubes and their application in organic electronics

Organic heterojunction is indispensable in organic electronic devices, such as organic solar cells (OSCs), organic light-emitting diodes (OLEDs) and so on. Fabrication of core-shell nanostructure provides feasible and novel way to prepare organic heterojunction, which is beneficial for miniaturization and integration of organic electronic devices. Fabrication of nanotubes which constitute the core-shell structure in large quantity is the key for the realization of application. In this work, a simple and convenient method to prepare nanotubes utilizing conjugated copolymer of perylene diimide and dithienothiophene (P(PDI-DTT)) was demonstrated. The relationship between preparation condition (solvent atmosphere, solution concentration and pore diameter of templates) and morphology of nanostructure was studied systematically. P(PDI-DTT) nanotubes could be fabricated in regular shape and large quantity by preparing the solution with appropriate concentration and placing Anodic Aluminum Oxide (AAO) template with nanopore diameter of 200 nm in the solvent atmosphere. The tubular structure was confirmed by scanning electron microscope (SEM). P(PDI-DTT) nanotubes exhibited electron mobility of 0.02 cm2V-1s–1 in field effect transistors under ambient condition. Light emitting nanostructures were successfully fabricated by incorporating tetraphenyl ethylene (TPE) into polymer nanotubes.有机异质结（Organic heterojunction）在有机电子器件中不可或缺，例如有机太阳能电池（OSCs）、有机发光二极管（OLEDs）等。核壳纳米结构的制备为有机异质结的制备提供了可行且新颖的途径，这有利于有机电子器件的小型化与集成化。大量制备构成核壳结构的纳米管是实现其应用的关键所在。本研究报道了一种简便易行的方法，利用苝二酰亚胺与二噻吩并噻吩共轭共聚物（P(PDI-DTT)）制备纳米管。系统研究了制备条件（溶剂气氛、溶液浓度与模板孔径）与纳米管形貌之间的关联。通过配制适宜浓度的溶液，并将纳米孔直径为200 nm的阳极氧化铝（AAO）模板置于溶剂气氛中，即可制备得到形貌规整且产量可观的P(PDI-DTT)纳米管。扫描电子显微镜（SEM）证实了该管状结构的存在。在大气环境下的场效应晶体管测试中，P(PDI-DTT)纳米管的电子迁移率可达0.02 cm²V⁻¹s⁻¹。将四苯乙烯（TPE）掺入聚合物纳米管后，成功制备出发光纳米结构。
