Abstract:
Thermally activated delayed fluorescence (TADF) organic materials achieved either by subtle manipulations of intramolecular or intermolecular charge transfer and their applications for giving OLEDs with high external quantum efficiency (EQE) and their working mechanisms will be presented.
