Redox-mediator enhanced electrochemiluminescence under non-aqueous conditions

(acac) because the required excitation pathways were either thermodynamically inaccessible or initiated at the same potentials as competing reactions involving the direct electrochemical oxidation of the luminophore. These findings establish that neutral iridium(iii) complexes can function as redox mediators in non-aqueous co-reactant ECL systems and provide mechanistic insight for extending redox-mediator-enhanced ECL to new luminophores and applications.
