Hole transporting materials with twisted aryl groups

Novel compounds, and in particular, novel molecules having twisted aryl groups are provided. In particular, the compounds include an aryl group at the ortho position relative to an amine nitrogen, thereby causing a twist within the compound from the plane of the aryl group due to the steric effect. As a result, this decreases the tendency of the molecules to pack closely and results in a higher solid state triplet energy due to reduced solid state π-stacking. Additionally, organic light emitting devices (OLEDs) comprising a layer including these novel compounds are provided.
