Enhanced EuIII ion luminescence and efficient energy transfer between lanthanide chelates within the polymeric structure in aqueous solutions

Four new binucleating symmetric bis(4-pyridine-2,6-dicarboxylic acids) have been synthesized and luminescence enhancement of their EuIII complexes by YIII ions observed.The results indicate that the mechanism of enhancement is based on the formation of a polymeric structure where EuIII ions and YIII ions are linked together by the ligands with the consequent transfer of absorbed energy along the polymer chain through several ligands toward the EuIII ion.The mechanism of energy transfer is probably different from the previously reported micellar co-luminescence where energy transfer occurs via the Foerster dipole-dipole mechanism.
