Fluorescent probes function based on the principle of fluorescence. When these probes absorb light at a specific wavelength, they reach an excited state. As they return to their ground state, they emit light at a different wavelength. This emitted light can be detected and measured, providing valuable information about the probe's environment and the processes occurring around it. In catalytic systems, this allows researchers to track changes in the reaction medium, detect the presence of certain species, and monitor the activity of the catalyst.
