Nanostructured TiO2 modified with acetohydrazide zinc porphyrin well-arrays for supramolecular solar cells

Nanostructured TiO2 electrode surface grafted novel assembly with acetohydrazide zinc porphyrin (ZnP) has been successfully organized by the metal ion (M, M = Mn2+, Co2+, Ni2+, Cu2+, Zn2+, Cd2+ and Hg2+) to bind the ZnP and different organic acid (Ai) ligands, in which Ai serves as anchoring group to functionalize the TiO2 electrode surface.
