Abstract

The aim of this work was the synthesis of nanohybrids of porphyrin rings with inorganic species and the study of their properties. Specifically the inorganic material LDH was combined with Protoporphyrin IX and Hemin in order to produce organic-inorganic nanohybrids. Initially the two porhphyrins were immobilized inside the layers of LDH under different conditions for each one. The two nanohybrids were characterized using IR, XRD and EPR spectroscopy. The ability of the nanohybrid LDH P.IX to act as a photosensitizer was examined during the photoxidation of an organic substrate and compared with the ability exhibited by the free protoporphyrin IX. The nanohybrid LDH hemin, which could be used as a model of transfer O2 to cells was studied with UV VIS spectroscopy and its properties were investigated in the presence of different reagents, while at the same time a comparison with the free hemin was made.
