Carbon-based nanomaterials have been widely studied in the past decade. Three approaches have been developed for the preparation of single-handed helical carbonaceous nanotubes. The first approach uses the carbonization of organopolymeric nanotubes, where the organic polymers are polypyrrole, 3-aminophenol-formaldehyde resin, and m-diaminobenzene-formaldehyde resin. The second approach uses the carbonization of aromatic ring-bridged polybissilsesquioxane followed by the removal of silica. Micropores exist within the walls of the carbonaceous nanotubes. The third approach uses the carbonization of organic compounds within silica nanotubes. This hard-templating approach drives the formation of helical carbonaceous nanotubes containing twisted carbonaceous nanoribbons. All of these helical carbonaceous nanotubes exhibit optical activity, which is believed to originate from the chiral π-π stacking of aromatic rings. They can be used as chirality inducers, and for lithium-ion storage.
在过去十年中，碳基纳米材料得到了广泛研究。已开发出三种制备单手螺旋碳质纳米管的方法。第一种方法是使用有机聚合物纳米管的碳化，其中有机聚合物为聚吡咯、3-氨基酚-甲醛树脂和间二氨基苯-甲醛树脂。第二种方法是使用芳环桥连聚倍半硅氧烷的碳化，随后去除二氧化硅。碳质纳米管壁内存在微孔。第三种方法是使用二氧化硅纳米管内有机化合物的碳化。这种硬模板法促使形成含有扭曲碳质纳米带的螺旋碳质纳米管。所有这些螺旋碳质纳米管都表现出光学活性，据信这源于芳环的手性π-π堆积。它们可用作手性诱导剂以及用于锂离子存储。
