(57) Abstract: Provided is an organic light-emitting device material having good color purity and capable of using a dye alone as a light-emitting layer. An organic light-emitting device material is a compound represented by the following general formula (I). General formula (I) In the formula, R 1 and R 2 may be the same or different and each represents an aryl group, a heterocyclic group or an aliphatic hydrocarbon group, and at least one of them represents an aryl group or a heterocyclic group. R 1 and R 2 may be linked to form a ring. R 3 represents a substituent, and m represents an integer of 0 to 4. However, when m is 2, 3 or 4, a plurality of R 3 may be the same or different. R 4 , R 5 and R 6 each represent a hydrogen atom or a substituent. Z 1 represents an atomic group forming a 5- to 7-membered ring. n represents 0, 1, and 2. |
