activated delayed fluorescence (TADF) properties were studied in detail. The photoluminescence quantum yields ΦPL of neat powder materials lie between 70 and 90% with emission colors from blue to yellow. Compound 9, with bulky ligands showing ΦPL = 90%, was used for detailed emission studies from T = 1.7 to 300 K. Up to T ≈ 70 K, 9 shows only long-lived phosphorescence with a radiative decay time of T1
