that simple isophthalamide molecules such as 1a are receptors for anions in chloroform.[5] In particular, fluoride and chloride ions bind more strongly to these receptors than bromide and iodide ions as a result of their size complementarity with the hydrogen-bond donor cleft created by the amide groups and their mutually ortho aryl proton. Unfortunately for our purposes, these receptors bind the halides with a 1:1 stoichiometry that is unsuitable for the formation of the desired template. The utilization of a cationic receptor as one of the ligands in the system could potentially solve this problem. Thus, 2 should include a chloride anion much more tightly in its cleft as a consequence of the increased acidity of the protons involved in substrate binding and the favorable electrostatics provided by the cationic nature of the pyridinium ring.
