Interest in chiral substances has mainly focused on the substances themselves, but not on the accompanying space, especially regarding the pore alignment. As a method to form both the chiral substance and the accompanying space, cylindrical self-assembly of uniform polystyrene nanoparticles with fructose is carried out in the presence of both carbon and sodium alginate, which is followed by heat treatment in an inert atmosphere. The carbonization generates fructose-derived honeycomb-like carbon walls with helically aligned nanopores left after the polystyrene decomposition. The diffuse reflectance circular dichroism measurements give peaks with opposite signs for the d- and l-fructose-derived cylindrical carbons. Circularly polarized light sensitivity in transient photoconductivity is confirmed apparently in the carbon-based helical structures. This sensitivity as well as straightforward formation of composites with another component to give helicity shows potential applications of the helically aligned pores.

圆柱碳上的螺旋孔对齐。

对手性物质的兴趣主要集中在物质本身上，而不是在伴随的空间上，特别是在孔排列方面。作为形成手性物质和伴随空间的方法，在碳酸钠和藻酸钠的存在下进行均匀聚苯乙烯纳米颗粒与果糖的圆柱自组装，然后在惰性气氛中进行热处理。碳化会生成果糖衍生的蜂窝状碳壁，在聚苯乙烯分解后会留下螺旋排列的纳米孔。漫反射圆二色性测量给出了衍生自d和l果糖的圆柱碳的相反符号的峰。在碳基螺旋结构中显然证实了圆偏振光在瞬态光电导中的敏感性。
