Synthesis and characterization of zeolite-encapsulated porphyrins

Abstract: porphyrins were prepared inside the large pores of the zeolite NaY by a process of sequential introduction of components followed by assembly inside the void space of the zeolite. The appropriate process chosen for the porphyrin synthesis was using the propionic acid solvent for reaction between pyrrole and benzaldehyde and this solvent was not destructive for zeolite. The resulting materials were purified by Soxhlet extractor. The zeolite-included porphyrins were identified for studies using UV-Vis and FTIR Spectroscopy and SEM techniques.
