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.

有机异质结在有机电子器件中不可或缺，例如有机太阳能电池（Organic Solar Cells，OSCs）、有机发光二极管（Organic Light-Emitting Diodes，OLEDs）等。制备核壳纳米结构为有机异质结的制备提供了可行且新颖的途径，有助于推动有机电子器件的小型化与集成化发展。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。本研究开发了一种简便易行的方法，利用苝二酰亚胺与二噻吩并噻吩的共轭共聚物（perylene diimide and dithienothiophene，P(PDI-DTT)）制备纳米管，并系统探究了制备条件（包括溶剂氛围、溶液浓度与模板孔径）与纳米结构形貌之间的关联。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（Anodic Aluminum Oxide，AAO）模板置于溶剂氛围中，可制备得到形貌规整、产量可观的P(PDI-DTT)纳米管。该管状结构经扫描电子显微镜（Scanning Electron Microscope，SEM）表征得以确认。在常温环境下的场效应晶体管中，P(PDI-DTT)纳米管展现出0.02 cm²·V⁻¹·s⁻¹的电子迁移率。将四苯乙烯（Tetraphenyl Ethylene，TPE）掺入该聚合物纳米管后，成功制备得到发光纳米结构。
