ORGANIC METAL COMPLEX, LUMINESCENT MATERIAL, DELAYED PHOSPHOR AND ORGANIC LIGHT EMITTING ELEMENT

摘要

An organic metal complex represented by the following general formula is useful as a light emitting material for an organic electroluminescent device and others. X represents O, S or -N(R 7 )-; Y represents O, S or -N(-SO 2 -R 8 )-; R 1 to R 8 represent H, an alkyl group or an aryl group; at least one of Z 1 and Z 2 represents a phenoxazin-10-yl group, a phenothiazin-10-yl group, a phenazin-10-yl group, etc.; M represents an element of the group 1 except for hydrogen, the group 2, the group 11, the group 12, or the group 13 of the periodic table; L represents a ligand; n is 1 to 3; and m is 0 to 2:
