Triphenylene derivatives, in particular for use as triplet matrix materials in organic electroluminescent devices, one of example of which is represented by formula I. The invention furthermore relates to a process for the preparation of the triphenylene derivatives and to electronic devices comprising the triphenylene derivatives. 

Materials for organic electroluminescent devices

The present invention relates, inter alia, to metal complexes having improved solubility, to processes for the preparation of the metal complexes, to devices comprising these metal complexes and to the use of the metal complexes. M(L)n(L')m formula 1 where the compound contains a moiety M(L)n of the formula (2) W is equal to the formula (3).

Metal complexes with organic ligands and use thereof in OLEDs

The present invention relates, inter alia, to metal complexes having improved solubility, process for the preparation of the metal complexes, devices comprising these metal complexes, and the use of the metal complexes.

Metal complexes

The present invention relates to novel conjugated polymers comprising spirobifluorene units and their use in optoelectronic devices, preferably in, for example, displays based on polymeric organic light-emitting diodes.
