摘要:
An organic luminescence is constituted by a pair of electrodes including an anode and a cathode, and an organic compound layer disposed between the pair of electrodes. The organic compound layer comprises a compound represented by the following formula (I): wherein R1 to R6 independently denote a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted aralkyl group, or a substituted or unsubstituted heterocyclic group, with the proviso that each pair of R1 and R2, R3 and R4, an R5 and R6 or of R1 and R6, R2 and R3, and R4 and R5 may be connected to each other to form a fused ring structure.
