Dibenzimidazolium Salts and Their Interactions with 1,5-dinaphtho-38-crown-10

Abstract

The use of imidazolium salts in mechanically interlocked molecules, like pseudorotaxanes, is of interest because they can be functionalized with side arms that allow for coordination chemistry. It has been previously shown that tetraakylbenzobisimidazolium salts successfully thread through crown ethers, such as 15DN38C10 or BPP34C10, to form pseudorotaxanes. As an extension of the results that were gathered about this novel template, it was our goal to explore the degree to which larger imidazolium salts interact with such crown ethers. This research focused on the interactions between 15DN38C10 and dibenzimidazolium cations that were tetra-substituted with methyl groups, butyl groups, and benzyl groups, respectively. These interactions were assessed using 1H NMR spectroscopy.
