Patent ID: 8273467

Claim:
An organic electroluminescent device, which comprises: a pair of electrodes; and an organic compound layer including a light-emitting layer between the pair of electrodes, wherein the organic compound layer comprises a compound represented by formula (III): wherein R 3 , R 5 , R 8 and R 13 each represents a hydrogen atom; R 4 represents a hydrogen atom, a phenyl group, a substituted phenyl group, an alkyl group, or a substituted alkyl group; R 6 , R 7 , R 9 , R 10 , R 11 , R 12 , R 14 and R 15 each independently represents a hydrogen atom or a substituent, when R 6 , R 7 , R 9 , R 10 , R 11 , R 12 , R 14 and R 15 each represents a substituent, the substituent may further have a substituent; and pairs of R 6 and R 7 , R 9 and R 10 , R 11 and R 12 , and R 14 and R 15 , each may combine to form a ring, wherein the compound represented by formula (III) has the lowest excited triplet energy level of from 65 kcal/mol (272.35 kJ/mol) to 95 kcal/mol (398.05 kJ/mol) and has a glass transition temperature of from 110 to 400° C.
