Abstract (EN): Copper(II) complexes with N3O2 Schiff base ligands [B: bis-(acetylacetone)-3-amino-bis(propylenediimine) = H-2(acac)(2)trien; C: bis-(acetylacetone)-3-methylamino-bis(propylenediimine)= H-2(acac)(2)Metrien] were encapsulated in the supercages of zeolite Y in a two-step process: (i) adsorption of copper(II) acetylacetonate in the supercage of the zeolite; (ii) in-situ Schiff base condensation of the copper(II) acetylacetonate complex with corresponding triamine. The resulting materials were purified by Soxhlet extraction. Bulk and surface chemical analysis, surface characterization (SEM, XPS), spectroscopic characterization (UV/Vis, FTIR), electron paramagnetic resonance and temperature-programmed desorption studies of the new materials provide evidence for the entrapment of Cu(II) complexes in the zeolite supercages.
