NOVELTY - Iridium complex of 2,3-bis-(4-trifluoromethyl-phenyl)-quinoxaline is new.    USE - In light-emitting element as luminescent substance or sensitizer of fluorescent compound, which is useful in light emitting device of electronic equipment; useful in photoelectronics device (claimed) e.g. dye sensitized solar cell.    ADVANTAGE - The light emitting complex provides light emitting element with favorable color purity. The light emitting element containing the light emitting complex exhibits red or reddish emission of light with favorable color purity, and it can be emits light efficiently. The organometallic complex has strong absorption corresponding to triplet metal to ligand charge transfer (MLCT) transition, and has comparatively strong absorption over the entire visible light region. Therefore, the organometallic complex can be used for a device utilizing absorption of visible light, e.g. a dye sensitized solar cell as its dye, so that a device with high conversion efficiency can be obtained. The organometallic complex is a preferable material for a photoelectronics device such as a dye sensitized solar cell and a light emitting element because a molecule in the triplet MLCT excited state is stable. The light emitting device including the light emitting element can be driven with low power consumption because it has preferable luminous efficiency. Therefore, electronic equipments with low power consumption can be obtained by applying the light emitting device to the display portion of the electronic devices, and for e.g., a telephone set that has long battery standing time, and the like can be obtained.
