Abstract
Through copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC) reactions, new pyrene-appended triazole- and triazolium-based fluorescent probes have been 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 C-HF- hydrogen bonding interaction and de-protonation that was accompanied by fluorescence "turn-on". Further, the experimental observations were well supported by 1H NMR spectroscopy and density functional theory (DFT) calculations.
