Title:
ORGANIC SEMICONDUCTOR ELEMENT, COMPOUND, ORGANIC SEMICONDUCTOR COMPOSITION, AND METHOD FOR PRODUCING ORGANIC SEMICONDUCTOR FILM
Document Type and Number:
WIPO Patent Application WO/2017/006765
Kind Code:
A1
Abstract:
The objective 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; and a method for producing an organic semiconductor film. An organic semiconductor element according to the present invention contains a compound that has a molecular weight of 2,000 or more and comprises 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 group represented by formula (1-1). In formula (1-1), Ar represents an aromatic heterocyclic group or an aromatic hydrocarbon group having 5-18 carbon atoms; Ca represents CR1R2; La represents an alkylene group having 1-20 carbon atoms; Lb represents an alkyl group having 9 or more carbon atoms; l represents an integer of 1-5; and * represents a site to be bonded with another structure.
