synthesized and their binding capabilities for anion recognition were investigated. The probes showed different fluorescence behavior in response to fluoride (F−) ions. The probe bearing a triazolium moiety, displayed a high selectivity towards F− ions via CH⋯F− hydrogen bonding interaction and de-protonation that was accompanied by fluorescence “turn-on”. Further, the experimental observations were
