Organometallic Complex, And Light-Emitting Element And Light-Emitting Device Using The Same
摘要：
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), R1 to R4 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, R5 to R13 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.
摘要（中）：

本发明的目的是提供能够发射磷光的物质。 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，R 1至R 4各自为氢，卤素元素，酰基，烷基，烷氧基， 芳基，氰基和杂环基。 此外，R 5至R 13各自为氢，酰基，烷基，烷氧基，芳基，杂环基和 吸电子基团。 具有这种结构的有机金属络合物可以发射具有更高发射强度的磷光。
