A multi-resonant thermally activated delayed fluorescence emitter with a twisted second-generation carbazole dendron showing suppressed concentration quenching and its use in solution-processed organic light-emitting diodes

The MR-TADF emitter 2,7-tBuCzNB contains twisted second-generation tert -butyl-carbazole dendrons and shows good solubility, narrowband green emission, high Φ PL and suppressed ACQ of its emission.
