Abstract

The present invention relates to metal complexes and to electronic devices, especially organic electroluminescent devices, comprising these metal complexes, especially as emitters, and in particular monometallic metal complex containing a hexadentate tripodal ligand in which three bidentate sub-ligands coordinate to a metal and the three bidentate sub-ligands, which may be the same or different, are joined via a bridge.
