제목 High-Performance Organic Thin-Film Transistors with Ordered π-Conjugated Copolmyer Films Based on BTBT.
초록 Organic thin-film transistors (OTFTs) have suffered from insufficient mobility for commercial viability despite their intrinsic advantages such as light weight, flexibility and simple fabrication. Here, we report high performance OTFTs fabricated by simple solution processing of π-conjugated semiconducting copolymers based on [1]benzothieno[3,2-b]benzothiophene (BTBT) and perylene/naphthalene diimide (PDI/NDI) derivatives. The OTFTs showed n-channel dominant behaviors with superior mobility compared to that made of other copolymers based on PDI/NDI. The morphology and molecular packing of the copolymer thin films analyzed through atomic force microscopy (AFM) and grazing incidence X-ray diffraction (GIXD) together explained the high performance of OTFTs. Furthermore, the OTFTs exhibited phototransistor behaviors under visible light, showing potential of PDI / NDI copolymer-based OTFTs in photosensor application.
