Abstract
Disclosed is an organic electroluminescent element which is characterized in that constituent layers including at least a phosphorescent light-emitting layer are provided between a pair of electrodes, and at least one of the constituent layers contains a compound represented by general formula (1). (In the formula, A1, A2 and A3 each represents a substituent; n1 and n2 each represents an integer of 0-3; X1 and X2 each represents an oxygen atom, a sulfur atom, an alkylene group, an imino group, a carbonyl group, a sulfoxide group or a sulfonyl group, or alternatively X2 represents a bonding hand; and Z1, Z2, Z3 and Z4 each represents an optionally substituted aromatic heterocyclic ring or an aromatic hydrocarbon ring, provided that all of the Z1, Z2, Z3 and Z4 are not aromatic hydrocarbon rings at the same time.)
