Proton-coupled electron transfer from a luminescent excited state.
A luminescent cationic iridium complex with a 2,2'-biimidazole ligand forms hydrogen-bonded 1 : 1 adducts with benzoate anions; photoexcitation of the metal complex in presence of 3,5-dinitrobenzoate triggers a proton-coupled electron transfer.
