<p>This invention relates to the use of electroluminescent metal complexes of the formula
wherein
the ring A,
represents an optionally substituted aryl group which can optionally contain heteroatoms,
the ring B,
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,
represents an acyclic carbene, or a cyclic carbene (ring C), which can optionally contain heteroatoms,
the ring D,
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,
M 1 is a metal with an atomic weight of greater than 40,
L 3 is a monodentate ligand, or a bidentate ligand,
Y is -C(=O)-, or -C(X 1 ) 2 -, wherein X 1 is hydrogen, or C 1-4 alkyl, especially hydrogen, and
y is 0, or 1, especially 0;
in electronic devices, especially organic light emitting diodes (OLEDs), as oxygen sensitive indicators, as phosphorescent indicators in bioassays, and as catalysts.</p> |
