Abstract

We synthesized two ribosyl-based fluorescent sensors. Both sensors have an anthracene as the fluorophore, but they differ in the recognition site for metal ions. One (3) has two ribosyl esters, and the other (6) has two triazole groups linked to two ribosyl esters. Among the metal ions examined in MeOH, compound 3 displayed a large chelation-enhanced fluorescence (CHEF) effect with Hg 2+ and Cu 2+ ions, and compound 6 displayed a large chelation-quenched fluorescence (CHQF) effect with Cu 2+ and Ni 2+ ions. The results demonstrated that the absence (sensor 3) and presence (sensor 6) of an incorporated bis-triazole group in a ribosyl-based fluorescent sensor conferred different preferences and distinct binding modes for metal ions.
