Design of multi-resonance thermally activated delayed fluorescence materials for organic light-emitting diodes

Two strategies to improve the performance of multiresonant thermally activated delayed fluorescence (MR-TADF) compounds are explored. These include incorporation of units to turn on aggregation-induced emission so as to permit use of MR-TADF compounds at high doping concentrations, and the use of heavy atoms to increase spin-orbit coupling to enhance reverse intersystem crossing rates. Preliminary photophysical investigations are presented.
