a

Values estimated from the onset of time-resolved PL spectra after the stabilization of 1CT or deconvoluted in order to obtain only the 1CT onset (Figure S42).

b

Values estimated from the onset of phosphorescence spectra. Spectra were collected with an 80 ms time delay and measured at 80 K.

c

ΔEST = 1CT – 3LE.

d

ΦPL measured for spin-coated films with a concentration of 1 wt % in the ZEONEX matrix using an integrating sphere connected to a Fluorolog-3.

e

Lifetimes estimated from monoexponential and biexponential decay fitting of the prompt and delayed regimes, respectively (Figure S46).
