摘要：A novel triazole-linked acetyl-beta-N-glucosyl anthraquinone 1 was conveniently synthesized through one-step click chemistry The functionalized glycoconjugate (1) exhibited a remarkable blue shift absorption and quenching fluorescence in the presence of trace amounts of Cu2+ presumably attributable to intramolecular charge transfer (ICT) which also displayed high selectivity over a series of other metal cations tested in acetonitrile The result yielded by fluorescence spectroscopy titration suggested a 2 1 ligand-to-metal complex which was further demonstrated by NMR spectroscopy titration Moreover the addition of Cu2+ to 1 also significantly altered its electrochemical behavior which was reflected via differential pulse voltammetry (DPV) measurements Such optically and electrochemically detectable metal-mediated sugar derivatives could be further used as biosensors for the recognition of multivalent carbohydrate-protein interactions (C) 2010 Elsevier Ltd All rights reserved
