This review discusses recent advances in TPE and its derivatives based small molecular materials (e.g., nanoaggregates, organic dots, silica and vesicles confined TPE-based materials) and polymers (e.g., polymer dots, metal–organic frameworks and covalent organic frameworks) for biological applications. The AIECL principles of TPE-based materials are explored, which are mainly through molecular aggregation, spatial confinement and rigid structure to restrict the motions of TPE and reduce non-radiative transitions to realize high ECL emission.

We discuss how these physicochemical complications challenge the development of atomistic models of SCE and how they impact the applicability of the computational hydrogen electrode, capacitance correction, grand canonical DFT, and Green function methods to model SCEs.
