Squaramide-based receptors: Synthesis and application to the recognition of polyalkyl ammonium salts

Article abstract of DOI:10.1016/0040-4039(95)00297-P

The design and synthesis of a novel series of receptors based on mixed squaric acid diamides subunits are reported. The use of the new tripodands as receptors for several tetraalkyl ammonium salts in chloroform was studied and the resulting complexes were
