Abstract The domain‐limited catalytic enhancement has opened novel avenues for the advancement of highly efficient aggregation‐induced electrochemiluminescence (AIECL). Herein, a (ECL) sensing platform is constructed through in situ encapsulation emission (AIE) molecules, tetraphenylethylene, within metal‐organic frameworks (NH 2 ‐MIL‐88). These are uniquely enriched with atomically dispersed active sites that serve as nanoconfined co‐reactant accelerators. This innovative design leads to creation an integrated AIE nanoconfinement reactor. Within this reactor, accelerators catalyze co‐reactants into reactive species (RS) situ, facilitating direct interaction molecules spatially confined composite. Density functional theory calculations and electrochemical electron paramagnetic resonance demonstrate ECL attributed localized amplification, where space formed by coordination self‐assembly alters activation energy barriers improves absorption capacity catalyzing K S O 8 SO 4 ·‐ OH ·− . Additionally, utilizing MATLAB‐mediated image technology deep learning algorithms, smartphone‐adopted self‐reporting AIECL imaging system designed achieve accurate intelligent analysis cardiac troponin I (cTnI). method presents advanced strategy enhance local RS concentrations via catalysis. developed offers facile screening cTnI monitoring.
