Abstract

The high sensitivity of fluorescence has prompted the use of fluorescent molecules 1–10 to probe the polarity and acidity 1–17 of the environment in biological 18 as well as synthetic systems. It was the aim of this research to develop probes with a large fluorescence quantum yield, absorbing in the visible and showing a large dependence of the fluorescence quantum yield or emission maximum on the polarity or acidity of the environment. The development ...
