Abstract
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(R7)—; Y represents O, S or —N(—SO2—R8)—; R1 to R8 represent H, an alkyl group or an aryl group; at least one of Z1 and Z2 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:
Claims14
An organic metal complex represented by the following Formula (1):
- wherein, in Formula (1), X represents an oxygen atom, a sulfur atom, or —N(R7)—;
- Y represents an oxygen atom, a sulfur atom, or —N(—SO2—R8)—;
- R1 to R8 each independently represent a hydrogen atom, an alkyl group which may be substituted by an alkoxy group, an aryl group or an aryloxy group, or an aryl group which may be substituted by an alkyl group, an alkoxy group, an aryl group or an aryloxy group;
- Z1 and Z2 each independently represent a hydrogen atom, an alkyl group which may be substituted by an alkoxy group, an aryl group or an aryloxy group, an aryl group which may be substituted by an alkyl group, an alkoxy group, an aryl group or an aryloxy group, or a group represented by any of the following Formulae (A) to (E), provided that at least one of Z1 and Z2 represents a group represented by any of the following Formulae (A) to (E);
- M represents lithium, sodium, potassium, rubidium, cesium, beryllium, magnesium, calcium, strontium, barium, copper, silver, gold, zinc, cadmium, mercury, boron, aluminum, gallium, indium, or thallium;
- L represents a ligand that is not encompassed by the following formula:
- n represents an integer of from 1 to 3;
- and m represents an integer of from 0 to 2:
- wherein, in Formulae (A) to (E), R21 to R28, R31 to R38, R41 to R49, and R51 to R70 each independently represent a hydrogen atom or a substituent, provided that R21 and R22, R22 and R23, R23 and R24, R25 and R26, R26 and R27, R27 and R28, R31 and R32, R32 and R33, R33 and R34, R35 and R36, R36 and R37, R37 and R38, R41 and R42, R42 and R43, R43 and R44, R45 and R46, R46 and R47, R47 and R48 R 51 , and R52, R52 and R53, R53 and R54, R55 and R56, R56 and R57, R57 and R58, R59 and R60, R61 and R62, R62 and R63, R63 and R64, R65 and R66, R66 and R67, R67 and R68, and R69 and R70 each may be bonded to each other to form a cyclic structure.
