Structure of copper(II) complexes adsorbed on functionalized polyhedral oligomeric silsesquioxane

The 3-amino-1,2,4-triazole-modified silsesquioxane nanoplatforms have been prepared and characterized. The silsesquioxane nanocages readily react with CuX2 in aqueous solution to form copper complex-substituted silsesquioxanes. Adsorption isotherms of CuX2 from aqueous solution were studied at 25 °C. The electronic and ESR spectral parameters indicated that the copper ion is in a distorted-tetragonal symmetry field.
