Abstract

Complexation of Eu³⁺ with three diglycolamide-functionalized calix[4]arene (C4DGA) ligands was investigated by UV-Vis and luminescence spectroscopy measurements in acetonitrile medium. The complexation thermodynamics was studied by micro-calorimetry while structural information was obtained from DFT calculations.
