An enantiomerically pure siderophore type ligand for the diastereoselective 1 : 1 complexation of lanthanide(III) ions
A facile synthesis of a highly preorganized tripodal enterobactine-type ligand 1a-H₃ consisting of a chiral C₃-symmetric macrocyclic peptide and three tridentate 2-amido-8-hydroxyquinoline coordinating units is presented. Complex formation with various metal ions (Al(³+), Ga(³+), Fe(³+), La(³+) and Eu(³+)) was investigated by spectrophotometric methods. Only in the case of La(³+) and Eu(³+) wer...

Unsymmetrical tripodal ligand for lanthanide complexation: structural, thermodynamic, and photophysical studies.
Two tridentate and one bidentate binding strands have been anchored on a carbon atom to provide a new unsymmetrical tripodal ligand L for Ln(III) coordination. The ligand itself adopts a single conformation in solution stabilized by intramolecular hydrogen bonds evidenced in the solid state. The reaction of L with trivalent lanthanides provides different coordination complexes depending on the ...

Study of the complexation of 1,3-diethyl 2-(azulen-1-ylmethylene)propanedioate with lanthanide cations.
This work is devoted to the electrochemical characterization of 1,3-diethyl 2-(azulen-1-ylmethylene)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 (Sm(3+), Eu(3+), Yb(3+), Tb(3+)) was studied by ...
