本发明之课题系在于提供:发光亮度及效率已提高之青色磷光发光组件及该发光组件之材料。本发明之课题系借由如通式(1)所示之双(3-芳基胺基)二苯基金属化合物解决 097102447P01.bmp (式中,M系表示硅原子或锗原子;Ar^1、Ar^2系可相同亦可不同,表示芳基或杂芳基,该芳基上之任何氢原子也可被卤素原子、烷基、环烷基、烯基、芳基、芳烷基、烷氧基、或芳氧基取代,此外相邻之Ar^1、Ar^2也可直接、或隔介醚键、硫醚键、伸烷基、氧伸烷基、或硫伸烷基而键结)。

This invention provides a blue phosphoric light emitting element with enhanced brightness of the emitted light and efficiency f emission, and the material therefore. The blue phosphoric light emitting element uses a his (3-arylamino) diphenyl metal compound represented by the general formula (1): wherein M represents a silicon atom or a germanium atom, and Ar2 may be the same or different, and represent an aryl group or a complex aryl group, of which any hydrogen atom, an alkyl group, a cycloalkyl group, a alkenyl group, an aryl group, an ardkyl group, and adjoining Ar1 and Ar2 may be directly bonded, or ether bonded, thioether bonded, or bonded through an alkylene group, an oxaalkylene group, or a thiaalkylene group.
