Complex compounds having anionic ligands containing two P donors and the use thereof in the opto-electronic field

摘要

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. 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.
