An intermolecular locking strategy was proposed to improve both the solution processibility and photoluminescence efficiency of red TADF emitters for solution-processed OLEDs with an EQE up to 8.2% and an efficiency roll-off of 9.0% at 1000 cd m−2.

A highly efficient solution-processible TADF blue host is developed by molecular encapsulation. Due to the steric shield effect of the peripheral units, the triplet–triplet and triplet–polaron quenching of the TADF blue host are restricted.

We report a new emitter 3,4,5-3TCz-TTT based on a tris(triazolo)triazine acceptor that shows thermally activated delayed fluorescence and cross-compare its performance with the recently reported analogue, 3DMAC-TTT.
