Auto-organization modulation of tetrasubstituted tetrathiafulvalenes (TTF) in silica based hybrid materials

Anisotropic organization of electroactive organic bridging moieties in hybrid materials obtained by sol-gel chemistry is function of the interaction forces induced by the spacer between the TTF core and the four triethoxysilane groups. The silica-based hybrid solids are highly polycondensed and present different scales of organization (nanometric and micrometric).
