Although the preparation of single-handed helical inorganic and hybrid organic-inorganic nanotubes is well developed, approaches to the formation of single-handed organopolymeric nanotubes are limited. Here, left-handed helical m-phenylenediamine-formaldehyde resin and 3-aminophenol-formaldehyde resin nanotubes were prepared by using N-palmitoyl glucosamine that can self-assemble into left-handed twisted nanoribbons in a mixture of methanol and water. In the reaction mixture, the helical pitch of the nanoribbons decreased with increasing reaction time. The resin nanotubes were obtained after removing the N-palmitoyl glucosamine template, and circular dichroism spectroscopy indicated that the organopolymeric nanotubes had optical activity. Carbonaceous nanotubes were then prepared by carbonization of the 3-aminophenol-formaldehyde resin nanotubes.
尽管单手螺旋无机纳米管和有机-无机杂化纳米管的制备技术已相当成熟，但形成单手有机聚合物纳米管的方法却很有限。在此，通过使用N-棕榈酰葡萄糖胺，在甲醇和水的混合溶液中制备了左旋螺旋间苯二胺-甲醛树脂纳米管和3-氨基酚-甲醛树脂纳米管，N-棕榈酰葡萄糖胺能够自组装成左旋扭曲纳米带。在反应混合物中，纳米带的螺旋间距随反应时间的增加而减小。去除N-棕榈酰葡萄糖胺模板后得到树脂纳米管，圆二色光谱表明有机聚合物纳米管具有光学活性。然后通过对3-氨基酚-甲醛树脂纳米管进行碳化制备了碳纳米管。
