Cathodic Electrochemiluminescence of Meso-tetra(4-suffophenyl) porphyrin/Potassium Peroxydisulfate System
摘要
Abstract
A new electrochemiluminescence (ECL) system in aqueous solution was constructed by using meso-tetra(4-sulfophenyl)porphyrin (TSPP) as a luminophoreandpotassium peroxydisulfate (K2S2O8) as a reductive-oxidative coreactant.Upon sweeping from 0 V to-1.5 V,two cathodic ECL peaks were found simultaneously.One appeared at-0.8 V,which is corresponding to the reduction of TSPP,another at-1.2 V,that is attributed to the reduction of K2S2O8.And methylene blue could quench the ECL of TSPP effectively.In accordance with the linearity between quenching efficiency and the concentration of methylene blue,a method to determine methylene blue was established.The ECL mechanism was also studied through a series of experiments.关键词
