ORGANIC SEMICONDUCTOR MATERIAL, ORGANIC SEMICONDUCTOR FILM, ORGANIC SEMICONDUCTOR ELEMENT, AND ORGANIC THIN FILM TRANSISTOR (TFT)

摘要

PROBLEM TO BE SOLVED: To provide a novel organic semiconductor material having a high mobility, and also to provide an organic TFT using the same.;SOLUTION: The organic semiconductor material includes, in its molecule, a high molecular macromolecule containing one or more 5-atom rings, each containing one hetero atom, and a partial structure expressed by a general expression (2). In the continuous partial structure expressed by the general expression (2), the substituent groups are all joined HT (Head to Tail). In the general expression (2), X₂ is a hetero atom and R₁ is an alkyl group or a group substituted for an alkyl group.;COPYRIGHT: (C)2007,JPO&INPIT
