9-Mesityl-10-methylacridinium ion (Acr+-Mes) is a donor-acceptor molecule with much longer lifetime and higher energy electron transfer excited state than natural photosynthetic reaction centers. Unlike lucigenin coplanar geometry, Acr+-Mes has an orthogonal geometry. There no π conjugation between Acr+ Mes. Due to its special structure, it does not rely on strong alkalinity generate like lucigenin, which makes possible achieve chemiluminescence (CL) under weakly alkaline or neutral...
In almost all electrochemical systems for electrochemiluminescence (ECL) analysis, electrodes are connected with an external power source, either directly or via wireless energy transfer circuit.
