Description
Summary:Amine‐rich nitrogen‐doped carbon nanodots (NCNDs) have been successfully used as co‐reactant in electrochemiluminescence (ECL) processes. Primary or tertiary amino groups on NCNDs have been studied as co‐reactant sites for Ru(bpy)32+ ECL, showing their eligibility as powerful alternatives to tripropylamine (TPrA). We also report the synthesis and ECL behavior of a new covalently linked hybrid of NCNDs and Ru(bpy)32+. Notably, the NCNDs in the hybrid act both as carrier for ECL labels and as co‐reactant for ECL generation. As a result, the hybrid shows a higher ECL emission as compared to the combination of the individual components, suggesting the self‐enhancing ECL of the ruthenium complex due to an intramolecular electron transfer process. Pimp my light: Amine‐rich nitrogen‐doped carbon nanodots (NCNDs) are introduced as co‐reactant in electrochemiluminescence (ECL) processes. The luminophore, Ru(bpy)32+, displays an enhanced ECL intensity when covalently linked to NCNDs as a result of an intramolecular electron‐transfer process.
