ConspectusOver the past decade, experiments involving microdroplets have challenged framework of chemistry. These droplets constitute a multiphase system, where dynamic interplay between solid, liquid, and gas influences reactions. Multiphase systems are prevalent in nature possess unique physicochemical properties. However, chemistry, phase boundary reactivity is often overlooked because molecules experience "bulk" reactivity. biological processes, such as cell mitosis, sensor technology, organic synthesis, pollution remediation.Recently, our group has developed different strategies electrochemiluminescence (also called electrogenerated chemiluminescence, both shortened to ECL) microscopy imaging understand properties dynamics at electrified interfaces. ECL takes advantage luminophore that radically annihilates with strong oxidizing or reducing reagent. If enthalpy annihilation high enough, will be left an excited state radiatively decay, producing light. Thus, requires no incident light, analytical figures merit due light being emitted close interface (1-10 μm), providing insight into within electrode's proximity.This Account detail group's efforts discovering reactions environments exhibiting native triphasic (liquid|liquid|electrode) interfaces new phases formed (e.g., bubble nucleation electroprecipitation).
