The dicyclen–TPE zinc complex as a novel fluorescent ensemble for nanomolar pyrophosphate sensing in 100% aqueous solution†
Abstract
A dicyclen–TPE Zn(II) complex was developed as a fluorescent ensemble for pyrophosphate (PPi) in water. The complex was characterized by X-ray single crystal diffraction, which could selectively respond to PPi over other phosphates with a large enhancement of fluorescence intensity, and the detection limit was determined to be 22.8 nM.
