Electrogenerated chemiluminescence triggered by electroseparation of Ru(bpy)32+ across a supported liquid membrane

We demonstrate here for the first time the detection of electrogenerated chemiluminescence (ECL) upon selective, electrochemically triggered tris(2,2′-bipyridyl)ruthenium(II) (Ru(bpy)32+) transport across a supported liquid membrane doped with a lipophilic cation-exchanger. This approach allows one to separate the location of ECL generation from the sample compartment, thereby avoiding the contamination of the sample with compounds necessary for ECL
