ABSTRACT:
It is an object of the present invention to provide a substance which can emit red phosphorescence which is closer to the chromaticity coordinates of red according to the NTSC standard. The present invention provides an organometallic complex represented by the general formula (1), wherein each of R1 to R3 represents any one of hydrogen, a halogen group, an acyl group, an alkyl group, an alkoxyl group, an aryl group, a cyano group, and a heterocyclic group, and at least one of R1to R3represents an electron-withdrawing group; and M represents a Group 9 element or a Group 10 element, and when M is the Group 9 element, n=2, whereas when M is the Group 10 element, n=1. Such an organometallic complex can emit red phosphorescence with good spectral luminous efficiency which is closer to the chromaticity coordinates of red according to the NTSC standard.
