Specifically substituted benzofuro- and benzothienoquinolines and their use in electronic devices, especially electroluminescent devices. When used as charge transport material, charge blocker material and/or host material in electroluminescent devices, the specifically substituted benzofuro- and benzothienoquinolines may provide improved efficiency, stability, manufacturability, or spectral characteristics of electroluminescent devices and reduced driving voltage of electroluminescent devices.

Specifically substituted benzofuro- and benzothienoquinolines for organic light emitting diodes

A compound of formula (I), a material for an organic electroluminescence device comprising at least one compound of formula (I); an organic electroluminescence device which comprises an organic thin film layer between a cathode and an anode, wherein the organic thin film layer comprises one or more layers and comprises a light emitting layer, and at least one layer of the organic thin film layer comprises at least one compound of formula (I); an electronic equipment comprising the organic electroluminescence device; and a process for preparing the compound of formula (I). 

Nitrogen-containing heterocyclic compounds for organic light emitting devices

The present disclosure generally relates to phenylenediamine compounds, which may be used as precursors in preparing diazaborole compounds and phosphorescent diazaborole metal complexes. The present disclosure also relates to diazaborole compounds, diazaborole metal complexes, and electroluminescent emission materials and electronic devices thereof. The present disclosure further relates to processes for preparing the phenylenediamine compounds and diazaborole metal complexes.

Phenylenediamine compounds for phosphorescent diazaborole metal complexes

Disclosed herein are phosphorescent materials comprising a complex of a metal atom M selected from Ir, Pt, Rh, Pd, Ru and Os and at least one ligand L, wherein the ligand L is represented by formula (1). Also disclosed are organic electroluminescent devices including such phosphorescent materials.
