Abstract
The compound represented by the following general formula is useful as a material for an organic light emitting device. X1 and X2 represent O or S; Y1 and Y2 represent a single bond, O, S or C(Ra)(Rb); R1 to R22, Ra, and Rb represent H, a deuterium atom, or a substituent, but at least one of R1 to R22 is a substituent.
