摘要： An object of the present invention is to provide an organic electroluminescent element having optimal light emitting characteristics. The above problem is solved by an organic electroluminescent element having a light emitting layer containing a compound of formula (1) or a multimer compound having a plurality of structures of formula (1) and a compound of formula (2). (In formula (1), ring A, ring B, and ring C each represent an aryl ring or the like, X1 and X2 each independently represent O or N—R, and the R represents an aryl or the like. In formula (2), R1 to R10 each represent an aryl or the like.)

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.
