文摘

A novel fluorescence probe for d-glucose is formed by anionic dye NAHBDS and cationic boronic acid functionalized poly(benzyl viologen salts) q-BBV²⁺. The two-component probe showed reversible fluorescence ¡°on-off?response for d-glucose. For probe, the specific bonding way of anionic dye and cationic polymer quencher/receptor provides an appropriate microenvironment and multidimensional bonding sites which actively catch d-glucose molecule.
