Ligands based on a cyclam and a cross-bridged cyclam scaffold functionalised at N1 and N8 by 6-phosphonic-2-methylene pyridyl groups are described. A family of complexes has been prepared with Ln3+ (Lu, Tb, Yb, Eu). The solution, structural, potentiometric and photophysical data for these novel ligands and their complexes have been investigated, including solid-state study by X-ray diffraction as well as UV-Vis absorption and luminescence spectroscopy in water with interesting energy transfer properties.
