A molecular design approach to stabilize the molecular structure and reduce the

energy gap produced two high triplet energy host materials of o-CzCN and m-CzCN

compatible with the phosphorescent and TADF emitters. o-CzCN and m-CzCN can improve the external quantum efficiency and lifetime of both blue phosphorescent and thermally activated delayed fluorescent (TADF) OLEDs.
