This work is devoted to the electrochemical characterization of diethyl 2-[(E)-3-azulen-1-ylprop-2-enylidene]propanedioate by cyclic voltammetry and differential pulse voltammetry. The redox processes are established, analyzed and assessed to the particular functional groups at which they take place. The complexation behavior towards lanthanide metal ions (Sm3+, Eu3+, Yb3+, Tb3+) was studied by electrochemistry and UV-Vis spectroscopy.
