Fluorescent ratiometric thermometers based on dyads of tetraphenyl porphyrin and zinc-metallated tetraphenyl porphyrin

Abstract

Porphyrins and their derivatives are known for their ability to emit two fluorescence bands. We presented the results of the investigation of the intensity ratio dependence for these bands on temperature in the range of 25–75°C for non-metaled and metal-plated with zinc porphyrins, as well as porphyrin dyads in solutions of 1,2-dichloroethane. A comparative analysis of thermometric parameters of these molecules was carried out.
