Unprecedented Crystalline Super-Lattices of Monodisperse Cobalt Nanorods

Coalescence of initially produced nanospheres inside 3D super‐lattices may be the reason for the formation of ferromagnetic cobalt nanorods, monodisperse in length and diameter, from [Co(η3‐C8H13)(η4‐C8H12)] in the presence of stearic acid and hexadecylamine. The self‐organization of these nanorods...

Summary:Coalescence of initially produced nanospheres inside 3D super‐lattices may be the reason for the formation of ferromagnetic cobalt nanorods, monodisperse in length and diameter, from [Co(η3‐C8H13)(η4‐C8H12)] in the presence of stearic acid and hexadecylamine. The self‐organization of these nanorods into unprecedented hexagonal 2D and 3D super‐lattices has been studied by transmission electron microscopy (see picture).
