      Abstract: The peculiar spectroscopic, magnetic,   and chemical properties of lanthanide ions (4f block, Ln(III))   are particularly attractive for the design of functional   supramolecular devices if these ions can be selectively   introduced into organized self-assembled architectures. The   systematic investigation of a complete library of tridentate   receptors leading to nine-coordinate tricapped trigonal prismatic   sites upon coordination to Ln(III) allows the elucidation of the   factors governing the structural, thermodynamic, electronic,   magnetic, and spectroscopic properties of the final complexes.   The simultaneous use of Ln(III) as cement between the molecular   components of the supramolecular edifices and as functional   vectors of the devices has been realized in self-as sembled   polynuclear d-f and f-f complexes. Predetermined properties may   result from a judicious molecular programming of the nanometric   architecture leading to fascinating applications in luminescence,   magnetism, template syntheses, and liquid crystals
