Abstract

Four Zn (II)-tetra (carboxyphenyl) porphyrins in solution and bound to metal oxide (TiO2, ZnO, and ZrO2) nanoparticle films were studied to determine the effect of the spacer length and anchoring group position (para or meta) on their binding geometry and photoelectrochemical and photophysical properties. The properties of three types of anchoring groups (COOH and COONHEt3) for four Zn (II)-porphyrins (Zn (II)-5, 10, 15, 20- ...
