Co(II)-phthalocyanine (cOPc) was synthesized in the cages of a NaY faujasite matrix and in NaY with co-encapsilated highly dispersed Ti(IV) oxide species. 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.
