Arylboronic acids with strong fluorescence intensity changes upon sugar binding

Abstract

Boronic acids play an important role in the design and synthesis of chemosensors for carbohydrates due to their ability to reversibly bind with diol-containing compounds. In this regard, the availability of boronic acids that change fluorescence upon sugar binding is crucial for a successful sensor design endeavor. Herein, we report two boronic acids that show strong fluorescent intensity changes upon sugar binding: isoquinoline-7-boronic acid (7-IQBA) and phenoxathiin- 4-boronic acid (4-POBA).
