Title:
N-TYPE ORGANIC SEMICONDUCTOR MATERIAL, ORGANIC SEMICONDUCTOR FILM-FORMING COMPOSITION, ORGANIC SEMICONDUCTOR FILM AND METHOD FOR PRODUCING SAME, ORGANIC THIN-FILM TRANSISTOR AND METHOD FOR PRODUCING SAME, AND COMPOUND PRODUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2019/176634
Kind Code:
A1
Abstract:
Provided are an n-type organic semiconductor material that has better properties and in particular that when used for a transistor exhibits an excellent carrier mobility and a good atmospheric operational stability; an organic semiconductor film-forming composition containing the same; and an organic semiconductor film and an organic thin-film transistor containing the same. The n-type organic semiconductor material is represented by formula (I). (In formula (I), A1 and A2 each independently represent -O-, -N(RN)- or -P(RN)-. B1 to B4 each independently represent -N= or -C(RM)=, provided that at least one is -N=. RN and RM each independently represent a hydrogen atom or a substituent. X1 to X4 each independently represent an oxygen atom or a sulfur atom.)
