Abstract

Univalent oxidation of luminol and univalent reduction of lucigenin must precede reaction with O2.- if that reaction is to lead to luminescence. The assumption that luminol or lucigenin, per se, reacts with O2.- in a way leading to luminescence is incorrect, and leads to misinterpretation of results. The chemical reactions leading to the O2(.-)-dependent luminescences of luminol and of lucigenin are discussed.

摘要

鲁米诺的一价氧化和光泽精的一价还原必须先于与超氧阴离子(O₂⁻)的反应,若该反应要产生发光现象的话。认为鲁米诺或光泽精本身能以某种导致发光的方式与超氧阴离子反应的假设是不正确的,并且会导致对结果的错误解读。本文讨论了导致鲁米诺和光泽精依赖超氧阴离子发光的化学反应。
