摘要
The dithienothiophene (DDT)-based small molecules have been studied and shown high field-effect transistor (FET) characteristics as vacuum evaporated polymers have not been explored for organic thin-film transistors (OTFTs) applications, presumably as a result of their poor solubility. The synthesis and characterization of a new DTT-based copolymer, poly(2,6-bis(3-alkylthiophen-2- yl)dithieno-[3,2-b;2',3'-d]thiophene) (PBTDT), as an excellent solution processed semiconductor for OTFTs. High-mobility polymer semiconductors for OTFTs such as 3 require processing in toxic chlorinated solvents at high temperatures to avoid solution gelling complications during device fabrication. The dithienothiophene moiety, offers high FET mobility and also other equally important processing and performance attributes including room-temperature processability in environmentally friendlier nonchlorinated solvents at high temperatures to avoid solution gelling complications during device fabrication.
