Glass transition (Tg) and decomposition (Tdec) temperatures observed from DSC and TGA, respectively (10 °C/min, N2 atmosphere).
Absorption and emission (excitation = λabs max) spectra measured in THF solution (10–4 M).
Ionization energies of the films measured using PESA.
Eg estimated from the intersection of absorption and emission spectra.
Mobility value at zero field strength.
