Zusammenfassung
A lifetime-based optical sensor for the measurement of dissolved and gaseous carbon dioxide has been developed. The basic principle is radiationless energy transfer from ruthenium(II)-4,40-diphenyl-2,20-bipyridyl as luminescent donor to thymol blue (a common pH indicator) as acceptor, both embedded in a hydrophobic matrix. In the presence of carbon dioxide thymol blue is protonated and changes ...
