The decoration of SWNTs with supramolecular motifs is a common strategy for their subsequent noncovalent functionalization. However, due to the lack of a standard methodology, there are no quantitative measurements showing the extent to which the supramolecular equilibria are affected by one of the host‐guest couple being anchored to the SWNT. Here, we use a method we initially developed to quantify association of small organic molecules to the walls of SWNTs to compare association constants of two host‐guest systems, a Hamilton receptor‐cyanuric acid derivative and a crown ether‐ammonium couple, in solution and when the host is covalently attached to the SWNTs. Our data show that association does occur, but the stability of the complexes is significantly affected, as reflected in a sizable reduction in their association constant, when compared to solution.

测量单壁碳纳米管附近的超分子复合物的稳定性。

具有超分子基序的单壁碳纳米管的装饰是其随后的非共价功能化的常见策略。但是，由于缺乏标准的方法，因此没有定量的测量结果可以显示超分子平衡受锚固于SWNT的一对客座夫妇影响的程度。在这里，我们使用最初开发的方法来量化小有机分子与单壁碳纳米管壁之间的缔合，以比较溶液和溶液中两个宿主-客体系统（汉密尔顿受体-氰尿酸衍生物和冠醚-铵对）的缔合常数。当主机与SWNT共价连接时。我们的数据表明确实发生了缔合，但复合物的稳定性受到显着影响，这反映在其缔合常数的大幅降低中，
