Assembling Nanometer Nickel Particles into Ordered Arrays

Encapsulated nickel nanofibres: Ultrasmall 1-dodecanethiol-capped nickel clusters were synthesized by a modified Schiffrin reaction. The mean outer diameter of the particles is 3.2 nm. X-ray photoelectron spectroscopy and X-ray diffraction results indicate that the core is composed of metallic nickel, not nickel oxide. This monolayer-protected Ni cluster (Ni-MPC) can be assembled along the template of C12SH and alkane lamellae into ordered nanofibers (see figure.)
