A light-emitting-layer host material is provided as material for high-efficiency organic electroluminescent devices. The light-emitting-layer host material has a high excitation triplet level, and is capable of completely confining the triplet excitons of phosphorescent material. A high-efficiency and high-luminance organic electroluminescent device is provided by using the compound. The compound is a compound of general formula (1) having a bipyridyl group and an ortho-terphenyl structure. The organic electroluminescent device includes a pair of electrodes, and one or more organic layers sandwiched between the pair of electrodes, and uses the compound as constituent material of at least one of the organic layers.
