Self-assemblies formed by isonicotinic acid analogues axially coordinating with zinc porphyrin via pyridyl unit: synthesis and application in dye sensitized solar cells

A novel zinc porphyrin ZnP bearing a 1,3,5-triazine-2,4-diamine unit has been designed and synthesized to construct axial-coordinated assemblies with different anchoring groups. Then these assemblies were grafted onto TiO2 electrode surface and their corresponding solar cells were successfully fabricated. The performance of these devices were studied and discussed.127
