摘要
本文致力于测量瞬时自由基 Eo 的单电子氧化还原电位。这些值可在自由基的可逆氧化还原反应中通过已知 Eo 的参比对进行测量。本文介绍了几种瞬态自由基的 Eo。方便测量 Eo 的重要对象是醌/半醌自由基阴离子。讨论了测量短寿命瞬态热力学性质的一般问题。
The measurement of one-electron redox potentials of free radicals
The paper is devoted to the measurements of one-electron redox potentials of transient free radicals Eo. These values can be measured in the reversible redox reactions of radicals under investigation with a reference pair, which Eo is known. Several Eo of transient radicals are presented. The convenient and important objects for Eo measurement are quinone/semiquinone radical-anions. A general problem of measurement of thermodynamic properties of short-lived transients is discussed.
期刊介绍：
The Journal of Physical Organic Chemistry is the foremost international journal devoted to the relationship between molecular structure and chemical reactivity in organic systems. It publishes Research Articles, Reviews and Mini Reviews based on research striving to understand the principles governing chemical structures in relation to activity and transformation with physical and mathematical rigor, using results derived from experimental and computational methods. Physical Organic Chemistry is a central and fundamental field with multiple applications in fields such as molecular recognition, supramolecular chemistry, catalysis, photochemistry, biological and material sciences, nanotechnology and surface science.
