“…[8] On the other hand, incorporation of metal complexes inside the zeolite enhances the chemical and thermal stability of the occluded complexes owing to the zeolite shielding. [9][10][11][12][13] In many cases, zeolite inclusion is applied to avoid the polymerization and to strongly reduce the self-oxidation tendency of the complexes. Literature survey in this trend referred to the encapsulation of different types of ligands, such as porphyrins, phthalocyanines, Schiff bases, (poly) pyridines, amidate, and polyaza macrocyclic models, and in addition we have recently published iron(II, III) complexes of hydrazone.…”
