Research Progress on Spatially Resolved Measurements for Decipherment of Electrochemiluminescence Mechanisms
Electrochemiluminescence(ECL) refers to the luminescence process,in which excited luminophores are generated by electrochemical reactions and sequential chemical reactions.Generally,ECL can be generated through either the annihilation or the coreactant route,which is a surface-confined luminescence process.The thickness of ECL layer is controlled by the distribution of reaction intermediates near the electrode surface.Meanwhile,spatially resolved measurements are capable of directly measuring the distribution of excited luminophores or coreactant radicals in the vicinity of electrode surface,holding great promise for deciphering the ECL mechanisms.In this review,the research progress on ECL and the reaction mechanisms of different ECL systems are first briefly introduced.Then the applications of spatial resolution measurements,including scanning electrochemical microscopy,ECL microscopy and ECL self-interference spectroscopy in unraveling the mechanisms for ECL generation are summarized.Finally,perspectives and challenges in mechanistic studies of ECL generation are presented.
