spectroscopic methods. The S2 fluorescence of various SbTPP derivatives was observed for the first time. It
was revealed that the S2 fluorescence lifetime changed depending on the donor-ability of the ligand because
of the contribution of the charge separation to the S2 excited SbTPP, which was confirmed by transient
absorption spectroscopy.
