Abstract
The synthesis of a novel [2]rotaxane host system containing a bis(triazolium)acridine-based axle component is reported. (1)H NMR anion-binding titrations reveal that the rotaxane is able to recognise selectively the NO3(-) anion over a range of more basic oxoanions (AcO(-), HCO3(-) and H2PO4(-)) in a competitive organic-aqueous solvent mixture.
摘要
报道了一种新型的包含基于双（三唑鎓）吖啶轴组件的[2]轮烷主体体系的合成。（1）H NMR阴离子结合滴定表明，在竞争性有机-水混合溶剂中，该轮烷能够在一系列碱性更强的含氧阴离子（AcO(-)、HCO3(-)和H2PO4(-)）存在下选择性识别NO3(-)阴离子。
