Immobilised CU(II)-L-tyrosine methylester and Cu(II)-BOC-(L)-histidine complexes were prepared through covalently grafting the amino acid ligands onto chlorine-functionalised polystyrene. The steps of the syntheses were followed by IR spectroscopy. The ligand to central ion ratio was four in both anchored complexes, and the most probable coordination sites were the carboxylic, the amino and the phenolic OH groups and the imidazole nitrogens for the tyrosine methylester and the BOC-(L)-histidine, respectively.
