Lanthanides-TTF complexes displaying single molecule magnet behaviour and luminescence

Abstract

Lanthanide-based complexes have greatly contributed to the development of mol. magnetism in the last decade and more particularly in the branch of single mol. magnets (SMMs) . The main reasons are their large magnetic moments assocd. to their intrinsic large magnetic anisotropy. The splitting of the multiplet ground state of a single-ion in a given environment is responsible of the trapping of the magnetic moment in one direction in SMMs. However, the analyses of the crystal field effects on the magnetic anisotropy are not so common . A better understanding of the magneto-structural correlations in lanthanide-based complexes should provide tools to improve their potentialities. In this presentation we will focus on the specific magnetic properties of TTF-based lanthanide mononuclear and polynuclear complexes. We will show how optimize the SMM behavior playing on i) the modulation of the supramol. effects via chem. modifications of the TTF ligand , ii) simple mol. engineering modifying the electronic distribution and symmetry of the coordination polyhedron, iii) magnetic dilns. (soln. and doping) and iv) isotopic enrichment of the dysprosium .
