The present invention relates to compounds of the formula (1) which are suitable for use in electronic devices, in particular organic electroluminescent devices, and to electronic devices which comprise these compounds.
Arylboroxines in combination with zinc chloride and potassium tert‐butoxide were found to undergo the electron‐catalyzed cross‐coupling with aryl iodides to give the corresponding biaryls without the aid of transition‐metal catalysis.
The present invention relates to novel organic compounds comprising at least two different selections selected from the group consisting of N-phenyl carbazole, dibenzofuran, dibenzothiophene, triphenylene, aza-(N-phenyl carbazole), aza-dibenzofuran, aza-dibenzothiophene, and aza-triphenylene. The compounds are useful for organic light-emitting diodes. The compounds are also useful for charge-transport and charge-blocking layers, and as hosts in the light-emissive layer for organic light emitting devices (OLEDs).
