Disclosed is an organic light-emitting material which is characterized by being represented by the following general formula (1) and used in a light-emitting layer of a green light- emitting device. In the general formula (1), n1 is an integer of not less than 1 and not more than 3; R1 represents an alkyl group having 10 or less carbon atoms; Ar1 represents a monovalent group which is derived from a monocyclic or condensed-ring aromatic hydrocarbon having 20 or less carbon atoms, and may have a substituent having 10 or less carbon atoms; and Ar2 represents a divalent group which is derived from a ring assembly including 1-3 rings, having 30 or less carbon atoms and being constituted by a monocyclic or condensed-ring aromatic hydrocarbon, and may have a substituent having 4 or less carbon atoms. Consequently, there is provided a more highly reliable organic light-emitting material with sufficiently good luminous efficiency and color purity which is suitable for constituting a green light-emitting layer. Also disclosed is a method for producing such an organic light-emitting material.
