Abstract
Prussian blue (PB) is the oldest coordination network discovered around 1706. This molecule-based material and its analogues (PBA) have been investigated through centuries for their fascinating physico-chemical properties. More particularly, their study at the nanoscale remains an area of intense ongoing research activity. This PhD work is devoted to the design of new and original magneto-optical nanomaterials based on PB and its analogues. To implement different optical features in PB-based nano-objects, two synthetic strategies have been proposed: (i) the post-synthetic functionalization of nanoparticles with luminophores; (ii) the design of nano-heterostructures with core@shell or core@satellites architectures, involving PBA and noble metal nanoparticles. An important effort has been given to investigate the properties of the obtained functional molecule-based nanomaterials by means of spectroscopy techniques, electronic microscopy and magnetic measurements. Through the conception and characterization of new nanosystems, this research work has aimed to demonstrate that the molecule-based multifunctionnal nanomaterials could be finally considered as potential candidates for future technological applications, including sensors technologies, biomedical applications or catalysis.
