The electrochemiluminescence (ECL) behavior of pyronin derivatives was reported. We found that these derivatives, as novel ECL emitters, generated an efficient emission phenomenon; is, they showed anodic using tri-propylamine (TPA) the coreactant and cathodic K 2 S O 8 coreactant. Because its remarkable luminescent performance, mechanism (reductive-oxidative oxidative-reductive) benzylthiol-sub...
