Abstract:
This invention relates to carbazole- or indolocarbazole-containing donor acceptor type compounds with an ortho substitution on the aromatic group that is connected to carbazole. This unique substitution pattern will provide materials with superior performance for host applications. These compounds can also be used as delayed fluorescent emitters.
