Abstract
A novel dopant according to the present disclosure includes an anion represented by the following Formula (1) and a counter cation. In Formula (1), Rand Rmay be each at least one group selected from a nitro group, a cyano group, an acyl group, a carboxyl group, an alkoxycarbonyl group, a haloalkyl group, a sulfo group, an alkylsulfonyl group, an halosulfonyl group, and a haloalkylsulfonyl group, or may be a group formed by Rand Rbonded to each other [—SO-L-SO—] (where L represents a haloalkylene group). The counter cation may be a radical cation represented by Formula (2), where Rand Rrepresent electron-withdrawing groups that may be bonded to each other to form a heterocycle, and Rto Rrepresent a hydrogen atom, a hydrocarbon group that may have a substituent, or a heterocyclic group that may have a substituent. The dopant is capable of forming an electroconductive composition that shows a high conductivity.
