摘要: Abstract The synthesis of new cyclam and cyclen derivatives (respectively L1 L2), able to efficiently coordinate Bi(III) are presented here. two ligands bearing different pendant arms (two-pycolyl (2-(2-hydroxyethoxy)ethyl)-2-aminoacetamide in trans position) were synthesized the aim obtain stable water soluble complexes. thermodynamic kinetic formation corresponding complexes aqueous solution studied by means NMR potentiometric investigations. fast complexation high stability encouraging for further application with alpha-emitting 213Bi isotope.
