Two highly efficient red phosphorescent Ir(iii) complexes were prepared by the introduction of rigid cyclometalating ligands.

Rigid electron donors (D) and acceptors (A) have been widely used in recent years for the construction of D-A type thermally activated delayed fluorescence (TADF) materials. However, the chromophore robustness...

Triplet-involved quenching processes lead to significant efficiency roll-off in phosphorescent organic light-emitting diodes (OLEDs). Thermally activated delayed fluorescence (TADF) materials can reduce the triplet exciton density in the emitting layer...

A highly efficient red thermally activated delayed fluorescence material was realized via the introduction of multiple acceptor units into a rigid backbone.

WOLEDs with stable natural white emission based on all-TADF emitters.

Three novel host materials (D-PY, S-CZ and S-TPA) based on 10,11-dihydro-5H-dibenzo[b,f]azepine (AZ) motif were designed and synthesized. The donor groups, triphenylamine (TPA) and carbazole (CZ), were attached at the different...

A new class of deep-blue phosphorescent [3+2+1] coordinated iridium (III) complexes containing phenyl-3H-imidazo[4,5-b]pyridine-based (C^C) bidentate ligands has been synthesized, characterized, and applied as phosphorescent dopants in the fabrication of vacuum-deposited...
