Description
High spin molecules and photomagnetic compounds are attracting increasing attention due to their potential interest in memory devices or optical switches. On the one hand, lanthanides have been recognized as viable building blocks for single molecule magnets (SMM) due to their strong single-ion anisotropy. On the other hand, octacyanometalates could be considered as interesting precursors not only for the drastic increase of their magnetization induced by visible light irradiation, but also for the design and synthesis of multicomponent architectures.
In this presentation, we focus on three topics that emerge from our research:
- High spin molecules based on polycyanometallates precursors and magnetic dendrimers viewed as promising nanomagnets.
- A family of photo switchable compounds, fully characterized by several techniques (XRD, SQUID, EPR, XMCD, …) in order to well understand the photo-magnetic processes that might vary from one compound to the others (spin transition, electron transfer, bond breaking).
- The design and the synthesis of hetero-tetra-metallic complexes, combining up to four different metallic ions in order to combine multi-properties, with the potential of featuring luminescent, magnetic and photo-switching properties (fig. 1).
