Selective detection and identification of toxic analytes such as trace gases hold significant
relevance in supramolecular host–guest functional systems. Identification becomes easier
when the detection tool is prone to fluorescence enhancement instead of quenching. A
judiciously designed substituted naphthopyran derivative was synthesized and its
interactions with several amine guests have been investigated. The probe displayed
enhancement in fluorescence signal on interaction with ammonia. Based on fluorescence …
