A first object is to provide an organometallic complex capable of exhibiting phosphorescence. In General Formula (G1), at least one substituent of R11 to R14 represents any of a halogen group, a haloalkyl group having 1 to 4 carbon atoms, and a cyano group. At least one substituent of R15 to R19 represents any of a halogen group, a haloalkyl group having 1 to 4 carbon atoms, and a cyano group. R20 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.

- Triazole derivative, and light-emitting device, and electronic device with the use of triazole derivative
-
It is an object of the present invention to provide a novel triazole derivative. Further, it is another object of the present invention to provide a light-emitting element having high luminous efficiency with the use of the novel triazole derivative. Moreover, it is still another object of the present invention to provide a light-emitting device and electronic devices which have low power consumption. A light-emitting element having high luminous efficiency can be manufactured with the use of a triazole derivative which is a 1,2,4-triazole derivative, in which an aryl group or a heteroaryl group is bonded to each of 3-position, 4-position, and 5-position, and in which any one of the aryl group or heteroaryl group has a 9H-carbazol-9-yl group.

- Inter- and innermolecular reactions of chloro(phenyl)carbene
-
Supramolecular photolyses of 3-chloro-3-phenyl-3H-diazirine (8) were performed within cyclodextrin (CyD) hosts to determine whether these toroidal inclusion compounds could alter the reactivity of the ensuing carbene reaction intermediate, chloro(phenyl)carbene (9). Remarkably, no intramolecular products stemming from carbene 9 could be detected. Instead, modified CyDs were formed via so-called innermolecular reactions. Hence, diazirine 8 was photolyzed in various conventional solvents to gauge the intermolecular reactivity of carbene 9. Relevant results were used to rationalize the CyD innermolecular reaction products.
