(a) Transient signals for selected wavelengths (dots) and fits (lines); (b) Decay associated spectra (DAS) describing the electronic dynamics of the Sb-corrole. DAS₁ shows the Soret to Q band transition and rise of the SE of the Q band. DAS₂ corresponds to triplet formation. The spectrum with a time constant of 10,000 ps represents the triplet decay and the decay of ground state bleach. The inverted sum of DAS₁, DAS₃, and DAS₄ is presented as relaxed fluorescence (black line), with an added offset to match the signal of DAS₂ at 700 nm; (c) two additional DAS showing cooling processes associated with a spectral blue shift and a narrowing of the respective peaks.
