Boronic acid sensors with double recognition sites: a review

Abstract

Boronic acids reversibly covalently bind to Lewis bases and polyols, which facilitated the development of a large number of chemical sensors to recognize carbohydrates, catecholamines, ions, hydrogen peroxide, and so on. However, due to the binding mechanism of boronic acids and analytes are not very clear, it is still a challenge to discovery sensors with higher affinity and selectivity. In this review, boronic acid sensors with two recognition sites, including diboronic acid sensors, and monoboronic acid sensors having another group or binding moiety were summarized. Owing to double recognition sites working synergistically, the binding affinity and selectivity of sensors can be improved significantly. This review may help researchers to sort out the binding rules and develop ideal boronic acid- ased sensors.
