The shape of things to come: Nanospheres, thermodynamically stable nanorods, and nanowires are selectively produced in solution from Co(η3-C8H13)(η4-C8H12) in the presence of oleic acid and various amines. The aspect ratio of the nanorods is controlled by the length of the alkyl chain of the amine. Nanorods with approximate dimensions of 9×40 nm (see Figure) are ferromagnetic at room temperature.
Dumestre et al. (2002) studied this question.
