Abstract
In this work two Schiff base porphyrins have been successfully synthesized The metal–ligand axial coordination assembling strategy has been used to organize two assemblies based on the two porphyrins appended isonicotinic acid ligands Further the assemblies were absorbed on the semiconducting TiO2 electrode surfaces by the carboxylic groups of isonicotinic acid ligands and their photovoltaic performances were performed under irradiance of 100 mW cm−2 AM 15G sunlight Photoelectrochemical studies show a significantly enhanced photovoltaic behavior for phenolbased zinc porphyrin assembly compared to pyridinebased zinc porphyrin assembly The UV–Vis absorption fluorescence spectra molecular orbital patterns and HOMO–LUMO energy gaps of the assemblies were also performed to further understand their photovoltaic features In addition the assembled modes of the assemblies immobilized on TiO2 electrode surfaces were also verified by transmission electron microscopyThe National Natural Science Foundation of China No 20871099 has supported this work We are very grateful to Prof Peng Wang Changchun Institute of Applied Chemistry Chinese Academy of Sciences for supplying device fabrication and measurement of solar cells We also acknowledge the support of Gansu Computing Center of china
