Synthesis of Aromatic Quaternary Ammonium Salts and Their Effect on Nanojar Crystallization
Martinon-Dupre, Thibaut Laurent Michel
Nanojars are a class of supramolecular coordination complexes that self-assemble from copperII ions, pz, and ions of large hydration energy in the presence of base discovered by the Mezei Lab of Western Michigan University. While much has been published about these assemblies, crystallization of certain anion-nanojars have proven to be futile due to inability to crystallize when Bu4N+ is used as a counterion. In this work, different synthesized counterions will be introduced to these anion-nanojar assemblies. These new quaternary ammonium salts include aromatic R-groups so it can establish IMFs with the nanojars: stabilizing the structure, normalizing the solubility, and inducing crystal growth. As it stands, one candidate, tribenzylmethylammonium nitrate has been synthesized in a mild procedure. The discovery of this salt lead to a new purification method in which future candidate salts will be synthesized.
