Abstract
An organic compound denoted by formula [1], where each of X1 and X2 is independently selected from an alkyl group optionally having a substituent, an aryl group optionally having a substituent, and an aralkyl group optionally having a substituent, each of R11 to R20 is independently selected from a hydrogen atom and a substituent, Y represents an alkyl group optionally having a substituent or an aryl group optionally having a substituent, and each of A1− and A2− independently represents a monovalent anion.
