Abstract
The design, synthesis and spectroscopic properties of novel polymerizable coumarin-based pH indicators are reported. They show a fluorescence response to pH in the highly alkaline pH region with calculated pKa values in the range of 12.2–12.5. Covalent immobilization of the indicators to polymer supports provides novel pH-sensitive materials that possess excellent photostability. The materials are sensitive to pH in a similar range and can be applied in optical pH sensors for measuring pH in various alkaline media.
