ZEOLITE-ENCAPSULATED COPPER(II) COMPLEXES WITH N3O2 SCHIFF-BASES - SYNTHESIS AND CHARACTERIZATION

Copper(II) complexes with N3O2 Schiff base ligands [B: bis-(acetylacet one)-3-amino-bis(propylenediimine) = H-2(acac)(2)trien; C: cetylaceton e)-3-methylamino-bis(propylenediimine)= H-2(acac)(2)Metrien] were enca psulated in the supercages of zeolite Y in a two-step process: (i) ads orption of copper(II) acetylacetonate in the supercage of the zeolite; (ii) in-situ Schiff base condensation of the copper(II) acetylacetona te complex with corresponding triamine. The resulting materials were p urified by Soxhlet extraction. Bulk and surface chemical analysis, sur face characterization (SEM, XPS), spectroscopic characterization (UV/V is, FTIR), electron paramagnetic resonance and temperature-programmed desorption studies of the new materials provide evidence for the entra pment of Cu(II) complexes in the zeolite supercages.
