Since several years we are interested in designing new tripodal ligands for assembling lanthanide-mediated polynuclear systems, whose helicoidal structure is reminiscent to biological motifs. In this contribution, we will present different aspects of the chemical design of suitable organic receptors (anchoring moiety, spacers) as well as structural and physico-chemical properties of various self-assembled three-dimensional edifices (tetranuclear, pentanuclear, ...), which were investigated by NMR, spectroscopy and other techniques. In addition, thermodynamic characteristics will be discussed with respect (i) to the control of self-assembly processes and (ii) to possible predictions in designing new supramolecular functional compounds.
