title: Intramolecular electron transfer from axial ligand to S2-excited Sb-tetraphenylporphyrin.
abstract: The S(2) state properties of Sb-tetraphenylporphyrin (SbTPP) derivatives were investigated using subpicosecond spectroscopic methods. The S(2) fluorescence of various SbTPP derivatives was observed for the first time. It was revealed that the S(2) fluorescence lifetime changed depending on the donor-ability of the ligand because of the contribution of the charge separation to the S(2) excited SbTPP, which was confirmed by transient absorption spectroscopy.
