Abstract

The development of an efficient sensor for the determination of the DMSO content in aqueous solution is highly desirable in a number of chemical industries. Presented herein is a ferrocene-conjugated iridium(III) complex, which exhibits remarkable capability to detect traces of DMSO (<1% v/v) in aqueous solution through a turn-on luminescence sensing mechanism. The extraordinary sensitivity and selectivity of this newly developed complex for DMSO renders it as one of the most powerful DMSO sensors known.
