Smectic mesophases of functionalized silver and gold nanoparticles with anisotropic plasmonic properties
Résumé
Silver and gold nanoparticle superlattices with a layered structure were obtained via grafting of mesogenic molecules onto a metallic cluster surface. For the Ag superstructures unusual orientational order of the mesogenic ligands and anisotropy of the assembly afforded tunable plasmonic properties.
