in DMF hampered the measurement of its transient spectra, we examined the dynamics of the photoexcited states of 2 and 4 in DMF. The energy levels of the ion pairs were calculated to be 1.41 eV for Dp+-Hp--Im and 1.19 eV for Dp'-Hp-Im-. Analysis of the transient absorption spectra of 2 and 4 reveals
