Abstract

A simple bridge solves a difficult architectural problem. Ligand H₄tpaen, with an ethylenediamine backbone that has ten donor atoms, yields ten-coordinate lanthanide complexes, thus providing highly effective protection of the metal center from interaction with the solvent molecules. As a result, the EuIII and TbIII complexes of (tpaen)⁴⁻ show a bright and long-lived luminescence in H₂O combined with high solubility and stability.
