Film Electrochemiluminescence Controlled by Interfacial Reactions Along with Aggregation-, Matrix-Coordination-, and Crystallization-Induced Emissions.

The utility of electrochemiluminescence (ECL) in analysis has been proven by its use in the interrogation of novel luminophores as well as the commercial applications of immunoassays. This Minireview discusses the recent advances in film ECL enhancements controlled by interfacial reactions along with aggregation-induced, crystallization-induced, matrix-coordination-induced and nanoparticle surface state emissions. These enhancement phenomena are anticipated to lead to applications toward biological and medical diagnosis. Interfacial ECL enhancements of nanoparticle films and an in-depth analysis of the application of this knowledge into development of optoelectronics follow. Finally, recent novel crystallization induced ECL enhancements and hypochromic shifts are provided. Future analyses of these film ECL enhancement phenomena will provide complementary information for the optimal implementation of next generation luminophores into thin film optoelectronic and sensing applications.
