Claim:
An organic electroluminescence device comprising: an anode; a cathode; and at least one organic layer, wherein the at least one organic layer comprises a light-emitting layer being provided between the anode and the cathode and containing at least one light-emitting material, and the at least one organic layer contains at least one compound represented by formula (I): wherein each of A 11 , A 12 , A 13 , A 14 and A 15 represents an N atom or C—R 11 , and the number of N atoms represented by A 11 to A 15 is an integer of 1 or 2; R 11 represents a hydrogen atom or a substituent, and at least one of R 11 represents an aryl group or an aromatic heterocyclic group; when a plurality of partial structures represented by the following formula (I-a) are present, each partial structure (I-a) may be the same with or different from every other (I-a); Q 11 represents a monocyclic aryl group or an aromatic heterocyclic group, and each Q 11 may be the same with or different from every other Q 11 , wherein when the aromatic heterocyclic group represented by Q 11 is substituted with a substituent, the substituent for the aromatic heterocyclic group represented by Q 11 is selected from the group consisting of an alkyl group, an alkenyl group, an alkynyl group, an aryl group, an amino group an alkoxy group, an aryloxy group, a heterocyclic oxy group, an acyl group, an alkoxycarbonyl group, an aryloxycarbonyl group, an acyloxy group, an acylamino group, an alkoxycarbonylamino group, an aryloxycarbonylamino group, a sulfonylamino group, a sulfamoyl group, a carbamoyl group, an alkylthio group, an arylthio group, a heterocyclic thio group, a sulfonyl group, a sulfinyl group, a ureido group, a phosphoric acid amido group, a hydroxyl group, a mercapto group, a halogen atom, a cyano group, a sulfo group, a carboxyl group, a nitro group, a hydroxamic acid group, a sulfino group, a hydrazino group, an imino group, a silyl group, a silyloxy group, and a phosphoryl group, wherein the substituent for the aromatic heterocyclic group represented by Q 11 may further be substituted; R 12 represents an alkyl group, and each R 12 may be the same with or different from every other R 12 ; and each of m and l represents an integer of from 0 to 4, and n represents an integer of 1, 2 or 3, provided that n+m is an integer of 2 or more, and n+m+l is 4:
