| description | To provide an organic EL device having a low voltage, high efficiency and extended lifetime characteristics, and a host material for use in the organic EL device. A host material for an organic EL device, including a compound represented by the following general formula (1), or a structural isomer thereof: wherein X represents N or C-H and at least one thereof represents N, L independently represents an aromatic hydrocarbon group, and R2 to R6 represent hydrogen, an aliphatic hydrocarbon group, an aromatic hydrocarbon group, an aromatic heterocyclic group, or a linked aromatic group in which two to five of these aromatic rings are linked to each other, provided that R2 and at least one of others do not represent hydrogen. |
