New Semiconducting Copolymers Containing Alkyl Quarterthiophene and Alkoxy Naphthalene Moieties for Organic Thin Film Transistors

다국어 초록 (Multilingual Abstract)

A π-conjugated alkyl quarterthiophene-based copolymer was synthesized by a Suzuki coupling reaction,and its optical, thermal, and electrochemical and organic thin film transistor properties were characterized. The copolymersshowed good solubility in common solvents such as chloroform and toluene, etc. The weight average molecularweight (Mw) of PQTHN and PQTON were found to be 9,200 with polydispersity of 1.2 and 30,600 withpolydispersity of 2.39, respectively. The structure of PQTHN and PQTON was confirmed using 1H NMR and FTIRspectroscopy. Solution-processed organic thin film transistors (OTFTs) using PQTON exhibited 6.96×10-4 cm2 V-1 s-1as mobility with an on/off ratio of 2.46×104.
