Abstract:
We aim to introduce photoactivated optical ion sensors based on a triggered ion exchange process as novel dynamic tools. The quantification of the acidity change upon photoactivation of spiropyran within an organic membrane phase during photoexcitation is described here for the first time, suggesting a large pK(a) change of more than 6 orders of magnitude.
