Abstract: This invention relates to electroluminescent metal complexes of the formula (I), wherein the ring A, formula (II), represents an optionally substituted aryl group which can optionally contain heteroatoms, the ring B, formula (III), represents an optionally substituted nitrogen containing aryl group, which can optionally contain further heteroatoms, or the ring A may be taken with the ring B binding to the ring A to form a ring; the group C, formula (IV), represents an acyclic carbene, or a cyclic carbene (ring C), which can optionally contain heteroatoms, the ring D, formula (V), represents an optionally substituted aryl group which can optionally contain heteroatoms, n1 is an integer of 1 to 3, m1 is an integer of 0, 1, or 2, m2 is an integer 0, or 1, M1 is a metal with an atomic weight of greater than 40, L3 is a monodentate ligand, or a bidentate ligand, Y is —C(?O)—, or —C(X1)2-, wherein X1 is hydrogen, or C1-4alkyl, especially hydrogen, and y is 0, or 1, especially 0; a process for their preparation, ele
