Selective excitation of concomitant electrochemiluminophores: Tuning emission color by electrode potential

Abstract

ECL in 3D: Selective electrogenerated chemiluminescence (ECL) of several ruthenium and iridium complexes simultaneously in solution can be controlled by electrode potential (see picture; λ em=emission wavelength). These luminescent redox systems create a range of new possibilities for multi-analyte ECL detection, assessment of interdependent electrochemical/ spectroscopic properties, and color tuning in light-emitting devices.
