    Abstract: An organic light-emitting element having high efficiency and long lifetime is provided. An organic light-emitting body is provided which includes a host having a high electron-transport property (n-type host), a host having a high hole-transport property (p-type host), and a guest such as an iridium complex and in which the n-type host and the p-type host are located so as to be adjacent to each other. When an electron and a hole are injected to such a light-emitting body, the electron is trapped by the n-type host and the hole is trapped by the p-type host. Then, both the electron and the hole are injected to the guest, and thus the guest is brought into an excited state. In this process, less thermal deactivation occurs and the working rate of the guest is high; thus, highly efficient light emission can be obtained.

    Abstract: Disclosed is a phosphorescent organometallic complex having: a 6-membered aromatic heterocycle having a nitrogen atom; iridium or platinum to which the nitrogen atom coordinates; and an aryl group which is bonded to an α-carbon of the nitrogen atom and is ortho-metalated with the iridium or platinum, where at least one of the aromatic heterocycle and the aryl group has an alicyclic hydrocarbon having an intramolecular carbon-carbon bridged bond as a substituent. The ability of the bulky structure of the alicyclic hydrocarbon to inhibit aggregation of the organometallic complex, concerted with the strong electron-donating property of the alicyclic hydrocarbon to the aromatic heterocycle or the aryl group, contributes to the increase in absorption coefficient and phosphorescent efficiency of the organometallic complex. The improved absorption coefficient and the phosphorescent efficiency allow the formation of a light-emitting element with excellent external quantum efficiency over 25%.
