摘要：New C3,4-disubstituted bis-triazolyl glycoligands that feature a glucosyl or galactosyl scaffold incorporating two pyrenyl groups were synthesized via the Cu^1-catalyzed azide-alkyne 1,3-dipolar cycloaddition reaction （Cue-AAC）. These compounds exert a major emission band corresponding to that of pyrene excimer and respond specifically to mercury with a markedly quenched fluorescence. The epimeric nature of the pyranoglycosyl scaffold is determined influential toward the selectivity of the sensors.
