    Abstract

    Lanthanide complexes are of increasing interest as biol. probes; a no. of different gadolinium complexes are used com. as contrast agents for magnetic resonance imaging (MRI). The aim of this work has been to extend the use of lanthanide complexes by incorporating them into dendritic ligand systems. The syntheses of new multinuclear lanthanide complexes based on kinetically stable cyclen-derived ligands will be presented. In each case cyclen units are attached to a central chromophoric core. Characterization of ligands and complexes has been achieved using ES and APCI mass spectrometry, 1H NMR and UV-vis spectroscopy. Luminescence spectroscopy has been used to probe the local environment around the lanthanide ions in aq. soln. and this anal. approach has proved esp. powerful when studying complexes with the potential for differentiated binding sites.
