Abstract

Provided are an organic transistor containing a compound represented by the following formula in a semiconductor active layer; a compound which improves carrier mobility when being used in a semiconductor layer of an organic transistor and exhibits high solubility in an organic solvent; an organic semiconductor material for a non-light-emitting organic semiconductor device; a material for an organic transistor; a coating solution for a non-light-emitting organic semiconductor device; and an organic semiconductor film for a non-light-emitting organic semiconductor device (each of X¹ and X² represents NR¹³, an O atom, or a S atom; A¹ represents CR⁷ or a N atom; A² represents CR⁸ or a N atom; R¹³ represents a hydrogen atom, an alkyl group, an alkenyl group, an alkynyl group, or an acyl group; each of R¹ to R⁸ independently represents a hydrogen atom or a substituent; at least one of R¹, R², R³, R⁴, R⁵, R⁶, R⁷, or R⁸ is a substituent represented by -L-R; L represents a divalent linking group having a specific structure; and R represents an alkyl group, a cyano group, a vinyl group, an ethynyl group, an oxyethylene group, an oligo-oxyethylene group in which a repetition number v of an oxyethylene unit is equal to or greater than 2, a siloxane group, an oligosiloxane group having two or more silicon atoms, or a trialkylsilyl group).
