The zeolites were characterized by XRD, IR and elemental analysis. The MPc complexes are best characterized by UV-Vis spectroscopy. For example Figure 2 shows the electronic spectra for FePc inside the zeolite and in H2SO4 after... 

Metal phthalocyanine complexes (MPc M = V, Co and Cu) encapsulated in zeolite-Y were prepared by in-situ ligand synthesis and characterized by chemical and thermal analyses and FT-IR, diffuse reflectance UV-vis and EPR spectroscopic techniques. The studies provided evidence for the encapsulation of MPc inside the supercages of zeolite-Y. The Pc moiety distorts from square planarity as a consequence of encapsulation. The encapsulated complexes exhibited enhanced styrene epoxidation activity with /e/-/-butylhydroperoxide compared to the neat complexes in homogeneous medium. The activity and product selectivity of the encapsulated complexes varies with the central metal atom.
