摘要：

A novel Salen-type ligand and its four complexes, [LnL(NO3)(3)] [Ln = La (1), Nd (2), Eu (3), Tb (4)], were synthesized. The X-ray single-crystal diffraction analysis indicates that the ML type complexes [LaL(NO3)(3)] and [NdL(NO3)(3)] are isomorphous. With a proton migration (or transfer) from the phenol function to the imine function, coordination of Ln to the ligand gives the ligand a zwitterionic phenoxo-iminium form. The luminescent property of the Tb(III) complex is described and some factors that influence the luminescent intensity were also discussed. (c) 2006 Elsevier B.V. All rights reserved.
