Abstract
A triphenylamine derivative is represented by General Formula (1).In General Formula (1), OR1 represents an alkoxy group having 2 to 8 carbon atoms. R2 to R6 each independently represent a hydrogen atom or an alkyl group having 1 to 8 carbon atoms. Ar1 and Ar2 each independently represent a hydrogen atom, an aryl group having 6 to 20 carbon atoms and optionally substituted with an alkyl group having 1 to 6 carbon atoms, an aryl group having 6 to 20 carbon atoms and optionally substituted with an alkoxy group having 1 to 6 carbon atoms, a cycloalkyl group having 3 to 10 carbon atoms, or a 3- to 10-membered heterocyclic group. Note that the case where Ar1 and Ar2 are both a hydrogen atom is excluded.
