The reaction center Photosystem II is a key component of the most successful solar energy converting machinery on earth: the oxygenic photosynthesis. Photosystem II uses light to drive the reduction of plastoquinone and the oxidation of water. Water-oxidation is catalyzed by a manganese cluster and gives the organism an abundant source of electrons. The principles of photosynthesis have inspired chemists to mimic these reactions in artificial molecular assemblies. Synthetic light-harvesting antennae and light-induced charge separation systems have been demonstrated by several groups. More recently, there has been an increasing effort to mimic Photosystem II by coupling light-driven charge separation to water oxidation, catalyzed by synthetic manganese complexes.
反应中心光系统II是地球上最成功的太阳能转换机制——光合放氧作用的关键组成部分。光系统II利用光能驱动质体醌的还原和水的氧化。水的氧化由锰簇催化,为生物体提供了丰富的电子来源。光合作用的原理启发化学家在人工分子组装中模拟这些反应。几个研究小组已经展示了合成光捕获天线和光诱导电荷分离系统。最近,人们越来越努力通过将光驱动电荷分离与由合成锰配合物催化的水氧化相耦合来模拟光系统II。
