Abstract: An organic emitter represented by formula (I):




having a highest occupied molecular orbital (HOMO) of more than 70% electron density localized on the Ar1Ar2N-L unit and having an energy of lower than 4.9 eV in absolute numbers, a HOMO-1 having more than 70% electron density localized on the BD unit and an energy higher than 4.75 eV in absolute numbers, and a lowest unoccupied molecular orbital (LUMO) having more than 70% electron density localized on the BD unit. A compound represented by formula (I), where BD is a group selected from the following formulas:




A material for an organic electroluminescence device, which contains the compound. An electronic equipment containing the organic electroluminescence device. A light emitting layer containing at least one host and at least one dopant, where the dopant contains the compound.
