We report a new synthesis method of fibrous carbon material with pores sizes that are precisely controlled at the Ångstrom level, by carbonization of two dimensional (2D) porous sheets of pillar[6]arenes. The 2D porous sheets were prepared by 2D supramolecular polymerization induced by oxidation of hydroquinone units of pillar[6]arenes. Owing to the hexagonal structure of pillar[6]arene, the assembly induced by 2D supramolecular polymerization gave hexagonal 2D porous sheets, and the highly ordered structure of the 2D porous sheets formed regular fibrous structures. Then, carbonization of the 2D porous sheets afforded fibrous carbon materials with micropores. The micropore size of the fibrous porous carbon prepared from pillar[6]arene was the same size as that of the starting material pillar[6]arene assembly.
我们报告了一种新的合成方法，通过二维（2D）多孔[6]柱芳烃片的碳化，可精确控制孔径在埃（Ångstrom）级别。2D 多孔片是通过[6]柱芳烃的氢醌单元氧化诱导的 2D 超分子聚合制备的。由于[6]柱芳烃的六方结构，2D 超分子聚合诱导的组装得到了六方 2D 多孔片，而 2D 多孔片的高度有序结构形成了规则的纤维结构。然后，2D 多孔片的碳化得到了具有微孔的纤维状碳材料。由[6]柱芳烃制备的纤维状多孔碳的微孔尺寸与起始材料[6]柱芳烃组装的微孔尺寸相同。
