    • The fluorescence of the titanyl porphyrin appeared around 600 nm upon an excitation at 540 nm (porphyrin Q-band), while the free-base porphyrin showed a fluorescence around 650 nm.

    • -1 L], the fitting of the titration curve was successful. In contrast, we could not fit the titration curve using the equally coordinating system, in which the metal ions coordinate to all ligands with the same constant.

    • The main reason for the environmental change should be switching of the entire conformation of the dendrimer through the complexation. It can be observed as the change in the molecular size by DLS (dynamic light scattering) measurements (in Supporting Information).
