摘要

Provided is a novel compound having a high lowest triplet excited level (T1 level), a narrow bandgap, and a shallow highest occupied molecular orbital (HOMO) level. A dibenzoxanthene compound is represented by formula [1] described in Claim 1. In formula [1], R1 to R7 are each independently selected from the group consisting of hydrogen, alkyl groups, aryl groups, heterocyclic groups, aryloxy groups, alkoxy groups, amino groups, silyl groups, and cyano groups.
