Abstract
An organic EL material according to the present invention includes a compound represented by the general formula (I). In the formula (I), R1 and R2 are each independently a hydrogen atom or any substituent, and are preferably each independently a substituent selected from the group consisting of a hydrogen atom, a cyano group, a halogen-substituted alkyl group, a halogen, a pyridyl group optionally having a substituent, and an electron-donating aromatic group. A is a substituent in which at least one heteroaryl group optionally having a substituent, or at least one aryl amino group optionally having a substituent is bonded to a carbon atom at the 4-position of the pyridine ring directly or through other aromatic group.
