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.
提供了新型化合物,特别是具有扭曲芳基团的新型分子。具体而言,这些化合物在胺基氮的邻位位置包含一个芳基团,从而由于立体效应在化合物中引起芳基团平面的扭曲。因此,这减少了分子紧密堆积的倾向,并导致由于减少了固态π-堆积而产生更高的固态三重态能量。此外,提供了包括这些新型化合物的有机发光器件(OLEDs)的层。
