Figure 6.
Femtosecond transient absorption measurements of compound DMA-QT in Tol (left) and DMF (right) obtained by pump-probe experiment (λexc = 400 nm). Panel (A), experimental 3D matrix reporting color-coded ΔA as a function of wavelength and time; Panel (B), representative spectra at different delay times and representative kinetics (inset) at different wavelengths, together with steady-state absorption (gray-shaded area), emission (green-shaded area or orange-shaded area), and triplet TA spectra (purple-shaded area as obtained by ns laser flash photolysis shown below); Panel (C), EAS (excited associated spectra) obtained by global analysis.
