1. A compound of formula (I) wherein n1 is 1, m2 is 0, M1 is Pt or Ir; if M1 is Pt, m1 is 1 and if M1 is Ir, m1 is 2; in the ligandthe 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 and
the ligandis selected from wherein R1 is hydrogen, halogen, nitro, cyano, C1-C4alkyl, C1-C4 perfluoroalkyl or C1-C4alkoxy, R2 is hydrogen, halogen, nitro, cyano, C1-C4alkyl, C1-C4 perfluoroalkyl, C1-C4alkoxy, —S—C1-C4alkyl, —O—C1-C4 perfluoroalkyl, —SO2X22, —CO2X22, wherein X22 is C1-C4alkyl; C6H4CF3 or optionally substituted —O—C6-C10aryl, R3 is hydrogen, halogen, nitro, cyano, C1-C4alkyl, C1-C4 perfluoroalkyl, C1-C4alkoxy, —S—C1-C4alkyl or —O—C1-C4 perfluoroalkyl, R4 is hydrogen or halogen, R5 is optionally substituted C6-C10aryl, C1-C4alkyl, C1-C4 perfluoroalkyl, C1-C4alkoxy or —O—C1-C4 perfluoroalkyl and Z1, Z2, Z3 and Z4 are independently of each other selected from the group consisting of hydrogen, C1-C8perfluoroalkyl and aryl, which aryl optionally may be substituted with C1-C8alkyl, halogen, C1-C8alkoxy or phenyl, which phenyl can optionally be substituted with halogen, C1-C8alkyl or C1-C8alkoxy, or Z1 and Z2 form an aromatic or heteroaromatic ring or Z3 and Z4 form an alkyl or heteroalkyl ring. |
