Zusammenfassung:Based on the calixarenes known ability to host anionic species, the preparation of some hybrid materials with polyoxometalates ions is aimed. The work presents our first attempts to evaluate the interaction between calixarenes (Cx) and polyoxometalates (POM) at the interface between two dispersion mediums as well as in the same solvent. The Cx-containing extracting solution was analysed with UV-Vis spectroscopy whereas the crystalline materials isolated from Cx-containing solutions were investigated by FTIR spectra. The experimental measurements suggest a possible Cx-POM interaction.
