  Abstract: The recent upsurge of interest in   contrast agents for magnetic resonance imaging, of luminescent   chemosensors for medical diagnostic, and lately, for optical   imaging of cells has generated an impressive momentum for the   coordination and supramolecular chemistry of trivalent lanthanide   ions. We shortly review the synthetic methods allowing the   introduction of these spherical ions with fascinating optical and   magnetic properties into elaborate mono- and polymetallic   edifices. We then illustrate these methods by selected examples   describing the use of (i) a coronand to produce luminescent   liquid crystals, (ii) derivatized calixarenes for 4f-5f element   separation, (iii) podates for the production of nanoparticles   with high relaxivity and for sensitizing the near-infrared (NER)   emission, and (iv) self-assembly processes for producing   functional bimetallic edifices
