Abstract

Five receptors (1–5) including two macrocyclic receptors have been designed and synthesized for the recognition of dicarboxylic acids. The receptors having an NO₂ group show inhibition in hydrogen bonding molecular recognition towards the dicarboxylic acid and this effect becomes more prominent in the case of macrocyclic receptors 4 and 5 in CHCl₃. The binding behavior of these receptors has been studied by UV-vis, fluorescence and 1 : 1 ¹H NMR binding studies.
