─ 1. Conducting molecular materials :
Synthesis of molecular materials precursors: electroactive ⺎-conjugated organic and or-ganometallic molecules (several examples of donor and acceptors: TTF; bis(dithiolene) complexes of Ni, Pd, Pt, Au; TCNQ. Functionalization/introduction of non-covalent inte-ractions: hydrogen, halogen, chalcogen. Intermolecular interactions in the solid – Open shell molecules: - neutral radicals, stabilization, delocalization – two-stage redox sys-tems (Würster, Weitz) – overlap interactions in the solid – mixed valence dimers – 1D materials – band structures – Peierls transition.
─ 2. Magnetic molecular materials:
Introduction to fundamentals of magnetism of the transition metals. Magnetism of the essential lanthanide ions for our society. Single-Molecule Magnets as potential materials for high-density data storage applications.
─ 3. Hybrid materials: The concept hybrid, definitions and synthetic strategies (sol-gel, grafting, self-assembly, intercalation, coordination)
Classification of hybrid organic-inorganic materials (classes 1 and 2). The main families of amorphous and crystalline hybrid materials (organo-mineral polymers, functionalized silica, coordination polymers (CPs or MOFs), hybrid polyoxometallates, halometallates, phosphonates). Crystalline structure-properties relationship (luminescence, photo- and electrochromism, ferroelectricity, multiferroics, semi-conductors).
─ 4. Nanomaterials:Definition, history, classification.
Mechanism of formation and stabilization of nanoparticles (thermodynamic and kinetic aspects).
Synthesis of organic and inorganic nanoparticles. Properties (photophysics and plasmonics).
Functionalization and bio-conjugation.
Nanomedicine (delivery of the active principle and outcome in the body).

This module aims at presenting the main families of functional hybrid organic-inorga-nic materials and nanomaterials, commonly encountered in applications of condensed matter physics (conducting and magnetic molecular materials), photonics (optical pro-tection, surface plasmon resonance sensing) or in health, especially in nanomedicine (diagnosis, therapy). A particular focus will be dedicated to the fabrication of hybrid systems present in many areas thanks to the complementarity provided by the consti-tuting organic and inorganic bricks. The main coupling methods of the complementary entities will be developed together with the experimental techniques to characterize the composition and structure of the hybrid architectures thus obtained.
