Patent ID: 8277954

Claim:
An organic electroluminescent device, which comprises: a pair of electrodes; and at least one organic compound layer between the pair of electrodes, the at least one organic compound layer comprises at least a light-emitting layer, wherein at least one of the at least one organic compound layer comprises at least one compound represented by formula (1): Formula (1): wherein A 1 and A 2 each independently represents a carbon atom or a nitrogen atom; Q 5 and Q 6 each independently represents an atomic group for forming an aromatic hydrocarbon ring or an aromatic heterocyclic ring in combination with A 1 and A 2 respectively, provided that Q 5 and Q 6 are not combined through a single bond, a divalent aromatic hydrocarbon ring group or a divalent aromatic heterocyclic ring group; A 31 to A 38 each independently represents N or C—R 31 to C—R 38 ; R 31 to R 38 each independently represents a hydrogen atom or a substituent; and R 1 to R 8 each independently represents a hydrogen atom or a substituent, wherein the at least one compound represented by formula (1) has a glass transition temperature of 130 to 450° C., and has the lowest excited triplet energy level of from 63 kcal/mol to 95 kcal/mol.
