BORON-NITROGEN POLYAROMATIC COMPOUNDS AND THEIR USE IN OLEDS

摘要

Boron-nitrogen polyaromatic compounds having a fused aromatic ring system are provided, where the compounds include a [1,2]azaborino[1,2-a][1,2]azaborine;;which is optionally fused to one or more aromatic rings or fused aromatic rings; wherein the fused aromatic ring system is substituted by one or more substituents, R, that are not fused to the aromatic ring system, selected from the group consisting of deuterium, halide, alkyl, cycloalkyl, heteroalkyl, arylalkyl, alkoxy, aryloxy, amino, silyl, alkenyl, cycloalkenyl, heteroalkenyl, alkynyl, aryl, heteroaryl, acyl, carbonyl, carboxylic acids, ester, nitrile, isonitrile, sulfanyl, sulfinyl, sulfonyl, phosphino, and combinations thereof; and wherein any two adjacent substituents, R, are optionally joined to form one or more non-aromatic rings. Devices, such as organic light emitting devices (OLEDs) that comprise light emitting materials are also provided.
