Benefitting from the concurrent intramolecular TBCT and TSCT of ortho-linked TADF materials, high kF and kRISC are achieved simultaneously and the devices using o-DCz-TRZ and BN-DMAc as emitters achieved high EQEs of 20.3% and 24.2%.
This review highlights organoboron-based multiple-resonance compounds’ synthetic strategies classified as one-pot borylation, one-shot borylation, and late-stage functionalisation, and explores material structure–photophysical property correlations.
π-Stacked through-space charge transfer materials as TADF emitters are highly attractive for OLEDs due to their enhanced TADF characteristics enabled by controlled molecular rotations.
MR-TADF emitters with narrow emission have been developed and are expected to become fourth-generation emitters for HD-OLEDs, with molecular design guidelines and commercial prospects outlined in this review.
Chiral bipolar hosts of (R/S)-L-2mCPCN are synthesized, which show high S1/T1 energy levels and clear circularly polarized luminescence. Solution-processable CP-OLEDs based on such chiral hosts were achieved via a chirality energy transfer process.
