Synthesis and aqueous anion recognition of an imidazolium-based nonacationic cup. Issue 98 (25th November 2021) - Wang, Pinpin
Abstract : An imidazolium-based nonacationic cup exhibited anionic recognition for nucleoside molecules such as ATP and NADH via C–H⋯A − ionic hydrogen bonds, hydrophobic effects, and electrostatic interactions in aqueous solution. Abstract : An imidazolium-based nonacationic cup (1 ·9X; X = PF6 − or Cl − ) was synthesized via step-by-step SN 2 reactions without using any template. The water-soluble 1 ·9Cl − as a molecular container can encapsulate anionic nucleoside triphosphate and dinucleotide molecules ( e.g., ATP and NADH) inside its cavity through hydrogen bonds and electrostatic interactions in aqueous solution.
