ORGANIC THIN FILM TRANSISTOR, ORGANIC SEMICONDUCTOR THIN FILM, AND ORGANIC SEMICONDUCTOR MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a compound which enables the achievement of a high carrier mobility when used for a semiconductor active layer of an organic thin film transistor, and has a high solubility in organic solvent; and an organic thin film transistor arranged by use of such a compound.SOLUTION: An organic thin film transistor comprises a semiconductor active layer which contains a compound including n repeating units expressed by the general formula (1-1) or (1-2) below. (In the general formulas, Cy represents a benzene ring, a naphthalene ring or an anthracene ring; Rto R, and Rto Rindependently represent a hydrogen atom or a substituent group; Arto Arindependently represent a heteroarylene group or an arylene group; Vand Vrepresent a divalent coupling group; "m" represents an integer of 0-6; "n" represents two or larger; and "p" represents an integer of 0-6.)
