Abstract Zinc(II), copper(II) and cobalt(II) metallated porphyrins/phthalocyanines and bis (4‐pyridyl) pyrrolidinofullerene ( 9 ) were used in a supramolecular approach for the sensitization of titania. Spectral properties of the chromophores were examined in the solid state showing strong absorptions at 700 and 800 nm for porphyrins and phthalocyanines, respectively. The interaction between the chromophores and a dual ligand was investigated spectroscopically. Titania‐based composites sensitized with 9 and cobaltous porphyrin exhibited the highest photocatalytic activity against both phenol and methylene blue under solar irradiation. Photodegradation intermediates were determined based on LC‐UV‐Vis‐MS analysis. It is expected that the composites will be applied for remediation of aqueous environmental samples from transparent and colorful pollutants.
