제목 Synthesis of New Poly(thienylenevinylene) Derivatives with High Crystallinity and Charge-Carrier Mobility Exceeding 1 cm2V-1s-1 for Organic Thin-Film Transistors
초록 Conjugated polymers have been attracting attention because of their suitability in a wide range of promising low-cost, flexible electronic applications such as organic thin-film transistors (OTFTs), organic photovoltaic cells (OPVs). We report synthesis and characterization of high performance p-channel conjugated polymers containing alkyl-substituted thienylenevinylene (TV) units as an active layer for OTFTs. Maximum charge-carrier mobility of PC6TV12T and PC12TV12T approached 0.47 and 1.05 cm2V-1s-1, respectively. The insertion of alkyl-substituted TV unit in the polymer backbone enabled a highly planar molecular structure and a high crystallinity in thin films as well as high solubility in common organic solvents. These polymers showed a very strong lamellar ordering up to fifth (500) order. Conjugated polymer-based complementary inverters with a high gain (~ 16) were successfully demonstrated by the inkjet printing of PC12TV12T (p-type) and N2200 (n-type).
