The development of potential-resolved electrochemiluminescence (ECL) systems with dual emitting signals holds great promise for accurate and reliable determination in complex samples. However, the practical application such is hindered by inevitable mutual interaction mismatch between different luminophores or coreactants. In this work, first time, precisely tuning oxygen reduction performance M–N–C single-atom catalysts (SACs), we present a luminol ECL system employing endogenous dissolved O2 as coreactant. Using advanced situ monitoring theoretical calculations, elucidate intricate mechanism involving selective efficient activation through central metal species modulation. This modulation leads to controlled generation hydroxyl radical (·OH) superoxide (O2·–), which subsequently trigger cathodic anodic emission, respectively. well-designed Cu–N–C SACs, their moderate oxophilicity, enable simultaneous ·OH O2·–, thereby facilitating ECL. As proof concept, employed principal component analysis statistical method differentiate antibiotics based on output dual-potential signals. work establishes new avenue constructing platform single luminophore coreactant precise regulation active intermediates.

Abstract Exploring advanced co‐reaction accelerators with superior oxygen reduction activity that generate rich reactive species (ROS) has attracted great attention in boosting luminol‐O 2 electrochemiluminescence (ECL). However, tuning for efficient and selective catalytic O activation to switch anodic/cathodic ECL is very challenging. Herein, we report enzyme‐inspired Fe‐based single‐atom catalysts axial N/C coordination structures (FeN 5 , FeN 4 © SACs) can specific ROS cathodic/anodic conversion. Mechanistic studies reveal sites prefer produce highly active hydroxyl radicals afford direct cathodic luminescence by promoting the cleavage of O−O bonds through N‐induced electron redistribution. In contrast, tend superoxide radicals, resulting inefficient anodic ECL. Benefiting from enhanced ECL, SAC‐based immunosensor was constructed sensitive detection cancer biomarkers.
