A first object is to provide an organometallic complex capable of exhibiting phosphorescence. In General Formula (G1), at least one substituent of R
11
to R
14
represents any of a halogen group, a haloalkyl group having 1 to 4 carbon atoms, and a cyano group. At least one substituent of R
15
to R
19
represents any of a halogen group, a haloalkyl group having 1 to 4 carbon atoms, and a cyano group. R
20
represents any of an alkyl group having 1 to 6 carbon atoms, a cycloalkyl group having 5 to 8 carbon atoms, an aryl group having 6 to 12 carbon atoms, and a heteroaryl group having 4 to 10 carbon atoms. M is either a Group 9 element or a Group 10 element. When M is a Group 9 element, n is 3, and when M is a Group 10 element, n is 2.
第一个目标是提供一种有机金属配合物,能够表现出磷光现象。在通用式(G1)中,R11至R14中至少一个取代基代表卤素基团、含有1至4个碳原子的卤代烷基团或氰基团。R15至R19中至少一个取代基代表卤素基团、含有1至4个碳原子的卤代烷基团或氰基团。R20代表具有1至6个碳原子的烷基团、具有5至8个碳原子的环烷基团、具有6至12个碳原子的芳基团或具有4至10个碳原子的杂环芳基团。M是第9族元素或第10族元素。当M是第9族元素时,n为3,当M是第10族元素时,n为2。
