| abstract |
The invention describes electronic devices comprising a metal complex compound having at least one ligand contain-ing 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-hybridised form, the radicals R3 and R4 are, indepen-dently of one another, hydrogen or an alkyl, cycloalkyl, alkenyl, cycloalkenyl, alkynyl, cyclo-alkynyl, alkylcycloalkyl, heteroalkyl, heterocycloalkyl, heteroalkylcycloalkyl, aryl, hetero-aryl, 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, hetero-cycloalkyl, hetero-alkyl-cycloalkyl, aryl, heteroaryl, aralkyl or heteroaralkyl radical having up to 40 C atoms and X=1, 2 or 3. The invention furthermore describes a process for the production of an electronic device of this type and processes for the generation of light or blue emission using a metal complex compound of this type. |
