摘要：

A new family of boronic acid-appended viologen quenchers has been synthesized containing two viologen subunits in a single quencher moiety. Relative to the single viologen-based quenchers previously developed in our laboratory, the bis-viologen ortho-boronic acid (BoB) compounds, in combination with the fluorescent dye, HPTS, display greatly enhanced Stern-Volmer quenching constants and much greater signal modulation in response to glucose. The superior performance is realized at lower quencher-to-dye ratios than are required for the single-viologen systems. Published by Elsevier Ltd.
