Highly efficient cuprous complexes with thermally activated delayed fluorescence and simplified solution process OLEDs using the ligand as host
Two strongly luminescent complexes, [Cu(czpzpy)(PPh 3 )]BF 4 ( 1 ) and [Cu(czpzpy)(POP)]BF 4 ( 2 ), bearing a new carbazole-based diimine ligand (czpzpy = 2-(9 H -carbazolyl)-6-(1 H -pyrazolyl)pyridine, PPh 3 = triphenylphosphine, and POP = bis[2-(diphenylphosphine)phenyl]ether) were synthesized and...
