The recent progress in pillar[n]arene-assisted/participated carbon nanotube hybrid materials were initially summarized and discussed. The molecular structure of pillar[n]arene could serve different roles in the fabrication of attractive carbon nanotube-based materials. Firstly, pillar[n]arene has the ability to provide the structural basis for enlarging the cylindrical pillar-like architecture by forming one-dimensional, rigid, tubular, oligomeric/polymeric structures with aromatic moieties as the linker, or forming spatially "closed", channel-like, flexible structures by perfunctionalizing with peptides and with intramolecular hydrogen bonding. Interestingly, such pillar[n]arene-based carbon nanotube-resembling structures were used as porous materials for the adsorption and separation of gas and toxic pollutants, as well as for artificial water channels and membranes. In addition to the art of organic synthesis, self-assembly based on pillar[n]arene, such as self-assembled amphiphilic molecules, is also used to promote and control the dispersion behavior of carbon nanotubes in solution. Furthermore, functionalized pillar[n]arene derivatives integrated carbon nanotubes to prepare advanced hybrid materials through supramolecular interactions, which could also incorporate various compositions such as Ag and Au nanoparticles for catalysis and sensing.
本文首先总结并讨论了柱芳烃辅助/参与的碳纳米管杂化材料的最新进展。柱芳烃的分子结构在制备有吸引力的碳纳米管基材料中可发挥不同作用。首先，柱芳烃能够通过以芳香部分为连接基形成一维、刚性、管状、低聚/聚合结构来扩大圆柱状柱状结构，或者通过用肽进行全功能化并形成分子内氢键来形成空间上“封闭”的通道状柔性结构，从而为扩大圆柱状柱状结构提供结构基础。有趣的是，这种类似柱芳烃的碳纳米管结构被用作气体和有毒污染物吸附与分离的多孔材料，以及人工水通道和膜。除了有机合成技术外，基于柱芳烃的自组装，如自组装两亲分子，也被用于促进和控制碳纳米管在溶液中的分散行为。此外，功能化的柱芳烃衍生物通过超分子相互作用将碳纳米管整合以制备先进的杂化材料，这还可以引入各种成分，如用于催化和传感的银和金纳米颗粒。
