Abstract
An important goal of our research is to develop reversible indicator systems that selectively respond to both anions. One approach is to based indicators on ion pairing reactions. Cation detection systems include an uncharged immobilized ionophore, an anionic dye and a cationic polyelectrolyte. The effect of added cation is to cause the anionic dye to dissociate from the cationic polyelectrolyte and form an ion pair with the ionophore/cation complex. Here we review results for cations and present new results for detection of an anion, fluoride. We have succeeded in developing indicators that are reversible and selective. The biggest problem we have encountered is slow response due to slow kinetics of the processes required for response.
