Bicarbazole-Derived High Triplet Energy P-type Host for Blue Thermally Activated Delayed Fluorescence Organic Light-Emitting Diodes

Student

Description:

Three p-type hosts with a high triplet energy (~3.06 eV) were synthesized and evaluated for thermally activated delayed fluorescence organic light-emitting diodes. The three hosts were designed to have a high triplet energy and controlled intermolecular interactions through molecular distortion by introducing bulky blocking groups into the 3,3'-bicarbazole core structure. The blue devices achieved a high external quantum efficiency of 25.6%.
