Electrogenerated chemiluminescence (ECL) is fundamentally dependent on the applied electrode potential, and measuring ECL intensity over a range of different potentials is commonly used to examine the underlying chemical reaction pathways responsible for the emission of light. Several research groups have now demonstrated that the applied potential can be exploited to selectively elicit ECL from: 1) multiple excited states within a single chemical species; 2) multiple emitters sharing a common co‐reactant; or 3) distinct ECL systems. This new generation of multiplexed ECL processes has been facilitated by the extensive development of novel electrochemiluminophores and instrumental approaches such as the near‐continuous collection of ECL spectra with CCD detectors during voltammetry or chronoamperometry experiments.
