摘要

•Excited-state dynamics absorption of Fe3+TMPyP complexes was performed.•Femtosecond Z-scan and ultrafast transient absorption techniques were employed.•Fast relaxations, with lifetimes around 2.0 picoseconds, were observed.•The fast relaxation was attributed to internal conversion relaxation processes.•μ-oxo-dimers slightly affect the relaxation of Fe3+TMPyP.•Fe3+TMPyP porphyrin can be useful for biomedical photothermal applications.
