Given their high FPL in mCP films we next proceeded to fabricate vacuum-deposited should lead to a decrease in bimolecular exciton quenching pathways by reducing the triplet density. comparison for reported MR-TADF DiKTa-based OLEDs with TPPO-tBu-DiKTa presented in this work (Table ); (h) Photograph of the OLEDs fabricated with 2 wt% TPPO-tBu-DiKTa.
