Abstract: The singlet-singlet annihilation within the series of Zn-porphyrin dendrimers by means of intensity dependent transient absorption experiments is studied. Analysis showed that sequential annihilation occurs within subunits up to four Zn-porphyrins in the dendrimers, and a full characterization of the transient absorption kinetics of the monomer over a spectral range from 450 to 730 nm is reported.
