Abstract:
Novel organic compounds comprising azaborine are provided. In particular, the compounds comprise a dibenzo-1,4,-azaborine core having a phenyl substituent on the boron atom, and aryl or heteroaryl substituents at positions 2 and 6 of the phenyl substituent. These compounds may be advantageously used in organic light-emitting devices to provide improved efficiency and lifetime.
