Competition titrations of Gd(III) (filled squares), Cu(II) (open circles) and Zn(II) (grey triangles) of L5 complexes against DTPA. The x-intercepts indicate the difference in pM between each heteropodal ligand and the competing poly(amino-carboxylate). Experimental conditions: 0.1 M KCl, pH 7.4, 25 °C.
