A facile method to prepare one-dimensional (1D) organometallic nanomaterials from various ethynyl-substituted molecules is reported. The reactions of 3-chloro-1-ethynylbenzene, -Bu-phenylacetylene and 4-ethynylbiphenyl with Cu ions in acetonitrile yield nanorod-shaped copper acetylides (Cu-C≡C-R) crystals. In the case of linear alkynes, namely, propyne, 1-pentyne and 1-hexyne, it was found that using an aqueous ammonia/ethanol mixed solvent instead of acetonitrile is a better approach to obtain 1D nanostructures. This procedure also enables us to prepare functional 1D nanomaterials. We demonstrate the preparation of a paramagnetic nanorod from the organic radical -ethynylphenyl nitronyl nitroxide, and fluorescent nanorods from 9-ethynylphenanthrene and 2-ethynyl-9,9'-spirobifluorene.
报道了一种从各种乙炔基取代分子制备一维（1D）有机金属纳米材料的简便方法。3-氯-1-乙炔基苯、-丁基苯乙炔和4-乙炔基联苯与铜离子在乙腈中的反应生成纳米棒状的乙炔铜（Cu-C≡C-R）晶体。对于线性炔烃，即丙炔、1-戊炔和1-己炔，发现使用氨水/乙醇混合溶剂代替乙腈是获得一维纳米结构的更好方法。该方法还使我们能够制备功能性一维纳米材料。我们展示了由有机自由基-乙炔基苯基硝酰基氮氧化物制备顺磁性纳米棒，以及由9-乙炔基菲和2-乙炔基-9,9'-螺二芴制备荧光纳米棒。
