POLYCYCLIC PHENYLPYRIDINE IRIDIUM COMPLEXES AND DERIVATIVES THEREOF FOR OLEDS

摘要

The present invention relates to metal complexes for use in electronic devices, and to electronic devices, especially organic electroluminescent devices, comprising these metal complexes, especially as emitters. The compounds claimed have the formula: M(L)n(L′)m formula (1), where the compound of the general formula (1) contains a substructure M(L)n of the formula (2) or formula (3), where A is the same or different at each instance and is a group of the formula (A) which follows. Also claimed are processes for preparing such compounds, one of which is shown by way of example (I).
