The chemical structure of the complexes is confirmed using UV–vis and IR spectroscopy and MALDI-TOF mass spectrometry. The dynamics of processes in photoexcited complexes was studied by femtosecond transient absorption spectroscopy. The lifetimes of (Cl)MnOEP exited states were determined and the effect of axial complexation on the dynamics of their relaxation was shown.
