Photoexcitation induces translocation of a common fluorescent pH and proton-transfer probe confined in reverse micelles

Proceedings of the National Academy of Sciences, Volume 123, Issue 25, June 2026.
SignificanceMolecular probes are assumed to reside in a well-defined local environment for the duration of an experiment. Here, we show that one species of HPTS, a widely used photoacid and pH-sensitive probe, resides hydrogen-bonded to the interface that …
