Abstract

Thanks to a smart regiospecific N-functionalization, a pyclen based ligand bearing one picolinate and two acetate arms organized in a dissymmetric manner was synthesized for Y3+ complexation, and compared to its symmetric analogue. The nature of the capping bonds around the metal coordination environment has a dramatic effect on the properties of the chelate, the natY3+ and 90Y3+ dissymmetric derivatives presenting enhanced thermodynamic stability and kinetic inertness.
