• emission of 1 gradually decreased without showing any other characteristic change in the spectra. Hydrogen bonding and charge–charge interactions interplay simultaneously in a cooperative manner for selectivity in the binding process. Keywords: anthracene coupled receptor; benzimidazolium-based receptor
