Title:
DOPANT, ELECTROCONDUCTIVE COMPOSITION AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2021/039463
Kind Code:
A1
Abstract:
A novel dopant according to the present disclosure contains an anion represented by formula (1) and a counter cation. In formula (1), each of R1 and R2 represents at least one group selected from among a nitro group, a cyano group, an acyl group, a carboxyl group, an alkoxycarbonyl group, a haloalkyl group, a sulfo group, an alkyl sulfonyl group, a halosulfonyl group and a haloalkyl sulfonyl group, or alternatively, R1 and R2 may combine with each other to form a –SO2-L-SO2- group (wherein L represents a haloalkylene group). The counter cation may be a radical cation represented by formula (2). (In the formula, R1 and R2 represent electron-withdrawing groups which may combine with each other to form a hetero ring; and each of R3 to R5 represents a hydrogen atom, an optionally substituted hydrocarbon group or an optionally substituted heterocyclic group.) This dopant is able to form an electroconductive composition that has a high conductivity.
