Resum:

The design of molecule-based systems displaying tunable optical and/or magnetic properties under external stimuli are interesting because of their potential applications in high-performance molecule-based electronics. As an example, 3D Fe/Co Prussian blue compounds exhibit a concomitant change in magnetic and optical properties due to a temperature- or light-induced metal-to-metal electron transfer (ET). Based on these remarkable properties we designed soluble molecular fragments of these coordination networks through a rational building-block approach in order to mimic their properties on a single molecule. In this seminar, the preparation of nuclear based cyanido-bridged Fe/Co complexes will be explained. In solution, these molecules reveal important optical and magnetic changes. These results motivated us to design new dinuclear [FeCo] complexes exhibiting both thermally and light induced electron transfer in the solid state.
