<p>A polymer compound, which contains a structural unit represented by formula (2) and at least one kind of structural unit that is selected from the group consisting of structural units represented by formula (1-1) to formula (1-3), is useful for the production of an organic transistor that has high field effect mobility. (In formulae (1-1)-(1-3), R1 represents a hydrogen atom, an optionally substituted alkyl group, an optionally substituted alkoxy group, an optionally substituted alkylthio group, an aryl group, a monovalent heterocyclic group or a halogen atom; R2 represents an optionally substituted alkyl group having 2 or more carbon atoms; E represents -O-, -S-, -Se- or -N(Ra)-; Ra represents a hydrogen atom, an optionally substituted alkyl group, an aryl group or a monovalent heterocyclic group; ring A represents an aromatic ring or a heterocyclic ring; n2 represents an integer of 0 or more; and n3 represents an integer of 1-3.) (In formula (2), Ar1 represents an arylene group or a divalent heterocyclic group; and m1 represents an integer of 3-10.)</p> |
