文摘

The facile synthesis of an organic electric conducting nanowire is described. The simple oxidation of 9-methylcarbazole by iron(III) perchlorate in a methanol/acetonitrile mixture under atmospheric pressure and temperature produces abundant nanowires without using a template. The nanowire consists of 9,9鈥?dimethyl-3,3鈥?dicarbazyl and has a rectangular nanowire shape with an average diameter of 397 卤 50 nm and length of 17 卤 5 渭m. The results of the elemental analysis, ¹H NMR, FT-IR, XPS, and ESR measurements revealed that the chemical composition of the nanowire is (dicarbazyl)_0.12(dicarbazylium路ClO₄^{鈥?/sup>)_0.88路H₂O. This result, combined with the UV鈥搗is鈥揘IR measurement, demonstrates that 9,9鈥?dimethyl-3,3鈥?dicarbazyl stacks in a mixed valence state. The nanowire is electroactive and has an electric conductivity of 3.0 脳 10鈥? S cm鈥?.}
