Patent number: 9425398
Abstract: The invention describes electronic devices comprising a metal complex compound having at least one anionic ligand containing two P donors, having the formula (I), in which R1 to R4 are, independently of one another, an atom or radical from the group comprising hydrogen, a halogen, R, RO—, RS—, RCO—, RCOO—, RNH—, R2N—, RCONR— and —Si(R)X(OR)3-X, where R=a C1-C40-hydrocarbon and X=1, 2 or 3, and E is a bridge atom from the group with carbon or boron, where an atom or radical from the group with hydrogen, halogen, —CN, R, RO—, RS—, RCO—, RCOO—, RNH—, R2N—, RCONR— and —Si(R)X(OR)3-X, where R=the C1-C40-hydrocarbon and X=1, 2 or 3, is optionally bonded to the carbon, and two radicals from the group with halogen, R, RO—, RS—, RCO—, RCOO—, RNH—, R2N—, RCONR— and —Si(R)X(OR)3-X, where R=the C1-C40-hydrocarbon and X=1, 2 or 3, are optionally bonded to the boron.

Patent number: 9082990
Abstract: The invention describes electronic devices comprising a metal complex compound having at least one ligand containing an N donor and a P donor having the formula (I), in which the carbons C1 and C2 are part of an aromatic or non-aromatic ring system F1, P and N are phosphorus and nitrogen, where the nitrogen is in sp2-hybridized form, the radicals R3 and R4 are, independently of one another, hydrogen or an alkyl, cycloalkyl, alkenyl, cycloalkenyl, alkynyl, cycloalkynyl, alkylcycloalkyl, heteroalkyl, heterocycloalkyl, heteroalkylcycloalkyl, aryl, heteroaryl, aralkyl or heteroaralkyl radical having up to 40 C atoms, and R1 and R2 are, independently of one another, an atom or radical from the group comprising hydrogen, halogen, R, RO—, RS—, RCO—, RCOO—, RNH—, R2N—, RCONR— and —Si(R)X(OR)3-X, where R=an alkyl, cycloalkyl, alkenyl, cycloalkenyl, alkynyl, cycloalkynyl, alkylcycloalkyl, heteroalkyl, heterocycloalkyl, heteroalkylcycloalkyl, aryl, heteroaryl, aralkyl or heteroaralkyl radical having up to 40 C atoms and
