Abstract

We report here on an attractive concept to integrate electrochemically triggered ion-selective transport across an ion-selective plasticized PVC membrane and electrogenerated chemiluminescence (ECL) as a detection technique. This will eventually form the basis for an alternate transduction mechanism for electrochemical ion sensors. To this end, the selective extraction of the ECL reagent Ru(bpy)32+ is demonstrated by an o-NPOE plasticized PVC membrane doped with lipophilic cation-exchanger. Chemical imaging of Ru(bpy)32+ electrotransported across the PVC membrane demonstrates the feasibility of this concept as a future trend for two dimensional ion sensing.
