Abstract

Abstract Ethynylated phenothiazine based fluorescent boronic acid probes were prepared. Sonogashira coupling reaction was used to introduce substituted phenylethynylene fragments to the phenothiazine fluorophore to extend the π-conjugation and to enhance the emission property. The photophysical properties and the binding properties of these probes with hydroxyl acids were investigated. We found that the probes with significant ICT effect ...
