A two-step process in the liquid phase was used: (i) adsorption of copper(II) acetylacetonate in the porous structure of the PILC, and (ii) in situ Schiff condensation of the copper(II) precursor complex with the corresponding triamine. The new materials were characterised by chemical analysis, surface techniques (SEM and XPS), X-ray powder diffraction, nitrogen adsorption isotherms and spectroscopic methods (FTIR, UV/Vis). These data indicate conclusively that the CuII complexes are encapsulated in the PILC, and that the entrapped complexes exhibit structural and electronic properties that are different from those of the free complexes. These differences can arise from distortions caused either by steric effects imposed by the structure of pillared clay, or by strong interactions with the matrix.
