convenient and efficient alternative to the classical Richman–Atkins methodology for obtaining PCTA and new derivatives is reported. The key macrocyclization step occurs in good yields as a result of a sodium template effect. The potentiality of lanthanide(III) complexes derived from these new PCTA ligands to act as paramagnetic contrastophores or luminophores is reported.
