摘要: An organic light-emitting device containing both a compound represented by the following general formula (1) and a compound represented by the following general formula (2) has a high light emission efficiency. The rings a to c each are a benzene ring that can be optionally condensed, R1 and R2 each represent a substituted or unsubstituted aryl group, etc., four of R31 to R35 each are a substituted or unsubstituted carbazol-9-yl group, but all of these four are not the same, and the remaining one is a hydrogen atom, a cyano group, etc.

摘要: A polycyclic aromatic compound represented by general formula (1) described below and having a bulky substituent in a molecule is used as a material for an organic device, whereby, for example, an organic EL device excellent in quantum efficiency can be provided. In particular, concentration quenching can be suppressed even if a use concentration is comparatively high, and therefore the present art is advantageous in a device production process. In formula (1) described above, R1, R3, R4 to R7, R8 to R11 and R12 to R15 are independently hydrogen, aryl or the like, X1 is —O— or >N—R (R is aryl or the like), Z1 and Z2 are a bulky substituent such as aryl, and at least one hydrogen in the compound represented by formula (1) may be replaced by halogen or deuterium.
