An organic light-emitting material characterized in that it is used in a light emitting layer in a green light emitting element and represented by the following general formula (1):
wherein: n
1
is an integer of 0 to 3; R
1
is an alkyl group having 10 carbon atoms or less; Ar
1
is a monovalent group which is derived from monocyclic or fused-ring aromatic hydrocarbon having 20 carbon atoms or less, and which optionally has a substituent having 10 carbon atoms or less; and Ar
2
is a divalent group which is derived from a ring assembly having 30 carbon atoms or less and being comprised of monocyclic or fused-ring aromatic hydrocarbon having 1 to 3 rings, and which optionally has a substituent having 4 carbon atoms or less. There can be provided an organic light-emitting material which has satisfactorily excellent light emission efficiency and high color purity as well as higher reliability and which is advantageously used to constitute a green light emitting layer, and a method for producing the same.
