Title:
ORGANIC SEMICONDUCTOR ELEMENT, COMPOUND, ORGANIC SEMICONDUCTOR COMPOSITION, AND ORGANIC SEMICONDUCTOR FILM AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2017/006703
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: an organic semiconductor element (especially, an organic thin film transistor) which has high carrier mobility and is capable of stably maintaining the carrier mobility even if stored for a long period of time under high temperature high humidity conditions; a compound; an organic semiconductor composition which uses this compound; an organic semiconductor film; and a method for producing this organic semiconductor film. An organic semiconductor element according to the present invention is provided with an organic semiconductor layer that contains a compound having a molecular weight of 2,000 or more and comprising a repeating unit represented by formula (1). In formula (1), A represents an electron acceptor unit; D represents an electron donor unit; and the D and/or A moiety has at least one monovalent organic group represented by formula (1-1). In formula (1-1), n represents an integer of from 2 to 30 (inclusive); each of R1, R2 and R3 independently represents an optionally substituted alkyl group, alkoxy group, aryl group or heteroaryl group; and * represents a site to be bonded with another structure.)
