电子转移

电子转移(Electron transfer,ET),是指电子在二个原子或其他化学物质(如分子等)之间的移动。电子转移是一种氧化还原反应,会改变两个反应物的氧化态。

许多生物体的机制涉及电子转移反应,包括氧气和血红素的结合、光合作用、呼吸作用和排毒。此外,能量转移的过程可视为两电子转移(两个同时作用,方向相反的电子转移),在这个情况下两个互相转移的分子距离很小。电子转移常和过渡金属错合物有关 ,但现在也有很多有机化学反应中出现电子转移的例子。

Electron transfer 电子转移

Electron transfer (ET) occurs when an electron relocates from an atom or molecule) to another such chemical entity. ET is a mechanistic description of a redox reaction, wherein the oxidation state of reactant and product changes.

Numerous biological processes involve ET reactions. These processes include oxygen binding, photosynthesis, respiration, and detoxification. Additionally, the process of energy transfer can be formalized as a two-electron exchange (two concurrent ET events in opposite directions) in case of small distances between the transferring molecules. ET reactions commonly involve transition metal complexes, but there are now many examples of ET in organic chemistry.
