Abstract

The reaction of 1,8-bis(2-hydroxybenzamido)-3,6-dioxaoctane (H2L) with lanthanide nitrates in MeCN afforded new binuclear lanthanide complexes (Ln = La-Nd, Sm-Yb or Y, 1-13) in high yields, and the molecular structures of 1 and 2 were established by X-ray crystallography. A photophysical study of the ligand H2L and of the binuclear complexes (Ln = Nd, Sm, Eu, Tb and Dy) has been performed and the quenching effect of coordinated water molecules was observed. The H2L and Tb complex exhibit an up-conversion process under OPO excitation at 660 nm. The magnetic properties of Pr and Gd complexes are also reported.
