The present invention relates to compounds of the formula (I), a process for their preparation and their use in organic light emitting diodes (OLEDs), especially as host for phosphorescent compounds. The hosts may function with phosphorescent materials to provide improved efficiency, stability, manufacturability, or special characteristics of electroluminescent devices. 

Heterocyclic bridged biphenyls

The present invention relates to electroluminescent devices, comprising a compound of the formula (I) as a component of the transporting/injecting and/or electron blocking layer. The compounds of formula (I) may function alone, or in combination with dopants to provide improved efficiency, driving voltage and/or lifetime of electroluminescent devices. 

Phenanthroazole compounds as hole transporting materials for electro luminescent devices

This invention relates to electroluminescent metal complexes of the formula (I), or (II), a process for their preparation, electronic devices comprising the metal complexes and their use in electronic devices, especially organic light emitting diodes (OLEDs), as oxygen sensitive indicators, as phosphorescent indicators in bioassays, and as catalysts. 

Electroluminiscent metal complexes with dibenzo[f,h] quinoxalines

The present invention relates to electronic devices, especially electroluminescent devices, comprising azapyrenes of formula (I), or formula (III), wherein Y, Y, Y, Y, X, Xand Xare independently each other N, or CR, with the proviso that at least one of the groups X, Xand Xis a group CR, Ris hydrogen, F, &#x2014;SiRRR, or an organic substituent, Ris hydrogen, F, &#x2014;SiRRR, or an organic substituent, or any of the substituents R, Rand R, which are adjacent to each other, together form an aromatic, or heteroaromatic ring, or ring system, which can optionally be substituted, m is an integer of 1 to 6, and R, Rand Rare independently of each other a C-Calkyl group, a C-Caryl group, or a C-Caralkyl group, which may optionally be substituted, and Q is a linking group; with the proviso that in the compound of formula (III) at least one of the substituents R, or Ris a group Q; especially as host for phosphorescent emitters, electron transporting materials, or emitter materials. The hosts may function with phosphorescent materials to provide improved efficiency, stability, manufacturability, or spectral characteristics of electroluminescent devices.
