ENCAPSULATION OF ETO-2,5-DIMETHYL-3,6-DIPHENYLPYRROLO[3,4-C]PYRROLE IN FAUJASITES

Faujasite-type zeolites were loaded by vapour phase deposition with to -2,5-dimethyl-3,6-diphenylpyrrolo[3,4-c]pyrrole. The amount of dye was determined by thermal analysis. The encapsulation of the dye inside t he micropore system was established by XRD, UV-VIS spectroscopy and ni trogen adsorption. The differences in the experimental results obtaine d for the Na and H forms of the same Y zeolite by NMR as well as IR sp ectroscopy point to specific interactions of the dye molecules with th e host material.
