Ratiometric Detection of Water in Acetonitrile with 9-Hydroxybenzo[b]Quinolizinium as Fluorosolvatochromic Probe.

Katy Schäfer1,2, Heiko Ihmels3,4.   

Abstract

The solvatochromic 9-hydroxybenzo[b]quinolizinium ion is shown to operate as fluorescent probe for the detection of water in acetonitrile. The dual fluorescence of this photoacid and its dependence on the content of water in the medium enable the ratiometric analysis of the fluorescence data. Graphical Abstract ᅟ.
