Claims17
A luminescent material for a light emitting device represented by any one of the following general formulae 3 to 14:
- wherein R1, R2 and R3 are H, CnH2n+1 (n is an integer of 1 to 10), N(CnH2n+1)2 (n is an integer of 1 to 10), COOCnH2n+1 (n is an integer of 1 to 10), F, Cl, Br, I, CN, an optionally substituted plenyl group, an optionally substituted naphthyl group or a phenyl methyl group, which may be the same or different from each other, provided that at least one of R1 and R2 is N(CnH2n+1)2 (n is an integer of 1 to 10), F, Cl, Br, I, CN, an optionally substituted phenyl group, an optionally substituted naphthyl group or a phenyl methyl group;
- and D is a ligand represented by the following general formulae 17 or 18:
- wherein R4, R5 and R6 are H, CnH2n+1 (n is an integer of 1 to 10), N(CnH2n+1)2 (n is an integer of 1 to 10), COOCnH2n+1 (n is an integer of 1 to 10), F, Cl, Br, I, CN, CF3, a furyl group, a thienyl group, an optionally substituted phenyl group or an optionally substituted naphthyl group, which may he the same or different from each other.
