Abstract
Provided is an electron transport material represented by formula (1):wherein X represents an oxygen atom or ═C(CN)2; R1, R2, R3, R4, R5, R6, and R7 each independently represent a hydrogen atom, a halogen atom, a linear or branched alkyl group, an alkoxy group, an aryl group, or an aralkyl group; R8, R9, and R10 each independently represent a hydrogen atom, a halogen atom, a linear or branched alkyl group, an aralkyl group, an aryl group, —R11—O—R12, or —R13—CO—O—R14; R11 represents a linear or branched alkylene group; R12 represents a linear or branched alkyl group; R13 represents a single bond or a linear or branched alkylene group; and R14 represents a linear or branched alkyl group, an aryl group, or an aralkyl group, provided that at least two or more groups of R8, R9, and R10 represent a group other than a hydrogen atom.
