我们的目标是引入基于触发离子交换过程的光激活光学离子传感器作为新的动态工具。本文首次定量研究了有机膜相中螺吡喃在光激发过程中光活化时的酸度变化，表明pK(A)有6个数量级以上的变化。
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 photo-excitation is described here for the first time, suggesting a large pK(a) change of more than 6 orders of magnitude.
