  It is an object of the present invention to obtain an organometallic complex that is capable of converting an excited triplet state into luminescence, a light-emitting element that can be driven for a long time, is high in luminous efficiency, and has a favorable long lifetime, and a light-emitting device using the light-emitting element. The present invention provides a light-emitting element that has a pair of electrodes (an anode and a cathode) and a light-emitting layer between a pair of electrodes, where the light-emitting layer includes an organometallic complex represented by the following general formula (5) and one of a compound that has a larger energy gap than the organometallic complex and a compound that has a larger ionization potential and a smaller electron affinity than the organometallic complex, and provides a light-emitting device using the light-emitting device.

  本发明的目的是获得一种有机金属配合物，能够将激发的三重态状态转化为发光，具有长时间驱动、高发光效率和良好长寿命的发光元件，以及使用该发光元件的发光装置。本发明提供了一种发光元件，其具有一对电极（阳极和阴极）和位于一对电极之间的发光层，其中发光层包括由下列通式（5）表示的有机金属配合物和具有比有机金属配合物更大能隙的化合物或具有比有机金属配合物更大离化势和更小电子亲和力的化合物之一，并提供使用该发光元件的发光装置。

  It is an object of the present invention to provide a substance capable of emitting phosphorescence. In addition, it is an object of the present invention to provide a light-emitting element that is excellent in chromaticity. One aspect of the present invention is an organometallic complex having a structure represented by a general formula ( 1 ). In the general formula ( 1 ), R 1 to R 4 are each any one of hydrogen, a halogen element, an acyl group, an alkyl group, an alkoxyl group, an aryl group, a cyano group, and a heterocyclic group. In addition, R 5 to R 13 are each any one of hydrogen, an acyl group, an alkyl group, an alkoxyl group, an aryl group, a heterocyclic group, and an electron-withdrawing group. An organometallic complex having such a structure can emit phosphorescence with higher emission intensity.

  本发明的目的是提供一种能够发出磷光的物质。此外，本发明的目的是提供一种色度优异的发光元件。本发明的一个方面是具有由通式（1）表示的结构的有机金属配合物。在通式（1）中，R1至R4分别是氢、卤素元素、酰基、烷基、烷氧基、芳基、氰基和杂环基中的任意一种。此外，R5到R13分别是氢、酰基、烷基、烷氧基、芳基、杂环基和电子吸引基中的任意一种。具有这种结构的有机金属配合物可以发出更高强度的磷光。
