Abstract

Exciplex-based fluorescence thermometers have been developed which should allow the nonintrusive real-time determination of temperatures in hydrocarbon liquids within 1°C at temperatures as high as 400°C. The two-candidate dopant molecules—1,3-bis-(1′-pyrenyl)-propane and 3-(4′-dimethylaminophenyl)-1-(1′-pyrenyl)-propane—are commercially available and may be used at concentrations as low as 1 ppm.
