Triplet dynamics reveal loss pathways in multi-resonance thermally activated delayed fluorescence emitters Multi-resonance thermally activated delayed fluorescence (MR-TADF) materials are of interest for light-emitting applications due to their narrow emission bandwidths and high photoluminescence quantum yields.

Excited-state dynamics of C3-symmetric heptazine-based thermally activated delayed-fluorescence emitters† Heptazine-based materials have recently emerged as a promising motif for thermally activated delayed fluorescence, as their near-zero or negative singlet–triplet energy gaps enable extremely fast reverse intersystem crossing (rISC) rates.
