Molecular receptor for binding quaternary ammonium salts and a large anion effect on the complexation
摘要:
An acyclic receptor 1 with a binding cavity surrounded by electron-rich aryl surfaces has been synthesized for binding quaternary ammonium salts through cation-pi interactions. The association constants of the receptor 1 with salts in CDCl3 depend on the anions due to the hydrogen bonds between the exchangeable protons in the receptor 1 and anions.
