Title:
POLYMERIC COMPOUND, ORGANIC SEMICONDUCTOR MATERIAL, AND ORGANIC TRANSISTOR
Document Type and Number:
WIPO Patent Application WO/2012/050102
Kind Code:
A1
Abstract:
[Problem] To provide a polymeric compound which increases the field effect mobility of an organic transistor when used in an active layer (organic semiconductor layer) of the organic transistor.
[Solution] A polymeric compound containing a structural unit represented by formula (1) (wherein R1 represents an alkyl group, an aryl group, or a heteroaryl group; and R2 represents a hydrogen atom, an alkyl group, an alkoxy group, an alkylthio group, an aryl group, or a heteroaryl group) and a structural unit represented by formula (2-1) or (2-2) (wherein Z1 represents -CR5=CR6-, -S-, -O-, -Se-, or -NR7-; R3, R4, R5, and R6 each independently represent a hydrogen atom, an alkyl group, an aryl group, a heteroaryl group, a halogen atom, a cyano group, or a nitro group; R7 represents a hydrogen atom, an alkyl group, an aryl group, or a heteroaryl group; and Z2 represents =S=, =CR5-CR6=, or =Se=).
