Optical probe for D-glucose based on cationic polymer quencher/receptor and anionic dye in aqueous solution

摘要

A novel fluorescence probe for D-glucose is formed by anionic dye NAHBDS and cationic boronic acid functionalized poly(benzyl viologen salts) q-BBV~(2+). 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.
