As expected the encaged complexes were immobilized and could not be removed by extraction procedures. Unexpected were reversible aggregations of the CoPc molecules, revealed from DR-UV-vis spectra. The phenomena were attributed to frequently observed (i) local enrichments of the CoPc molecules, i.e., their nonuniform distribution throughout the zeolite crystals, and (ii( local damages, facilitating the contact between CoPc molecules.
