Modern technological needs in the field of nanotechnology require the development of new multifunctional materials capable to maintain their properties in the smallest possible size. The key feature of multifunctional materials is that they combine many properties and are expected to be useful in applications, as one property can be used to control others by applying external stimuli. Towards the development of new materials that retain their properties at the nanoscale, a field with intense activity in recent years is that of molecular materials. The development of molecule-based electronic devices requires a deep understanding, control and utilization of the properties of charge and spin carriers at the molecular level. One class of molecular materials that has been extensively studied in the last decade are Single Molecule Magnets (SMMs), the synthesis of which follows a bottom-up approach based on the principles of coordination chemistry. In recent years MMMs have been synthesized that combine ferromagnetic/dielectric behavior as well as chirality and have been proposed as multifunctional materials. We synthesized Cu / Ln polynuclear complexes that exhibit SMM behavior and chirality due to the use of chiral ligands i.e. pure enantiomers. The complexes crystallize in polar point symmetry groups, a basic condition for the appearance of ferroelectric behavior from the crystalline material
