^a Reported as k_r (=k_f + k_p); however, k_p is negligible. ^b Reported as k_nr (=k_ISC + k_IC); however, it was noted that the CT → S₀ internal conversion was negligible and that the CT → T₁ recombination was the most important non-radiative decay process, ^c Degassed conditions ^d Indirect measurement at 510 nm/indirect measurement at 540 nm//direct measurement at 505 nm, ^e same value in toluene (Tol), cyclohexane and MeCN.
