ORGANIC SEMICONDUCTOR POLYMER HAVING QUINOXALINE RING IN MAIN CHAIN AND USED FOR ORGANIC THIN-FILM TRANSISTOR

摘要

PPROBLEM TO BE SOLVED: To provide a composite-structure polythienylquinoxaline derivative having a high charge mobility and a low shut-down state leak current, to provide a method for producing the same, and to provide an organic thin-film transistor using the polythienylquinoxaline derivative. PSOLUTION: An organic thin-film transistor is provided which uses a polythienylquinoxaline derivative prepared by introducing a quinoxaline ring having a high electron affinity, namely, having an n-semiconductor properties and simultaneously exhibiting p- and n-electric properties into a polythiophene having a p-semiconductor properties and includes a substrate, a gate electrode, a gate insulation layer, an organic active layer, and a source/drain electrode.
