a
Measured in toluene at room temperature.
b
Measured in neat film at room temperature.
c
Measured in the neat film free of oxygen.
d
The lifetimes and fractional contributions of the prompt (τPF) and delayed (τDF) decay components in neat film measured at 298 K.
e
Determined by cyclic voltammetry in neat films.
f
Deduced from the HOMO and the optical energy gap (Eg) values.
