Electrogenerated chemiluminescence (ECL) is the light generated and controlled by the application of a potential at an electrode surface through an electron transfer reaction.

Recently, the enthusiastic phenomenon of aggregation‐induced electrogenerated chemiluminescence (AI‐ECL) has come to light, examining a class of supramolecular assemblies and nanostructure that can emit stronger ECL than the corresponding unassembled system can do. This new concept brings together electrochemical and photophysical properties of aggregates and new fascinating and unexplored mechanisms for its generation.

The findings can lead to a new generation of bright emitters that can be used as ECL labels in immunoassays and different biosensors, where the change in the packing of the aggregated systems (ASs) can be monitored by an off/on ECL signal or even different colors.

The following chapter outlines the general principle and mechanisms of AI‐ECL together with the new emerging emitters in the field of metal complexes, organic molecules, and materials. Then, an overview of the main applications will be presented, focusing mostly on bioanalysis.
