Suppression of efficiency roll-off in solution-processed OLEDs using pyrimidine-based iridium complexes modified with sterically hindered groups
{{output}}
Three bis-cyclometalated iridium complexes Ir1-Ir3 were successfully synthesized through mild reaction conditions. All complexes exhibit emission peaks at 507-509 nm, with excellent photoluminescence quantum efficiencies (PLQY) ranging from 69% to 97%. Self-qu... ...
