ORGANIC THIN FILM TRANSISTOR, ORGANIC SEMICONDUCTOR MATERIAL FOR NON-LUMINESCENT ORGANIC SEMICONDUCTOR DEVICE AND APPLICATION THEREOF

摘要

PROBLEM TO BE SOLVED: To provide an organic thin film transistor having high carrier mobility.;SOLUTION: An organic thin film transistor containing a compound represented by the following formula in a semiconductor active layer. In the formula, x represents O, S or Se atom; R¹,R⁴,R⁵ and R⁸ to R¹⁰ represent hydrogen or halogen atom; R²,R³,R⁶ and R⁷ represent hydrogen atom, alkyl group, halogen atom or -L-R; one of R²,R³,R⁶ and R⁷ represents -L-R; L represents specific bivalent coupling group (however, bivalent coupling group represented by -CR'₂- is not directly coupled to mother nucleus; R represents alkyl group, cyano group, vinyl group, ethynyl group, oxyethylene group, oligooxyetylene group in which the repetition number v of oxyethylene unit is equal to 2 or more, siloxane group, oligosiloxane in which the number of silicon atoms is equal to 2 or more, or trialkylsilyl group.;COPYRIGHT: (C)2015,JPO&INPIT
