Photosynthesis is a process wherein the chromophores in plants and bacteria absorb light and convert it into chemical energy. To mimic this process, an emissive poly(ethylene glycol)-decorated tetragonal prismatic platinum(II) cage was prepared and used as the donor molecule to construct a light-harvesting system in water. Eosin Y was chosen as the acceptor because of its good spectral overlap with that of the metallacage, which is essential for the preparation of light-harvesting systems. Such a combination showed enhanced catalytic activity in catalyzing the cross-coupling hydrogen evolution reaction, as compared with eosin Y alone. This study offers a pathway for using the output energy from the light-harvesting system to mimic the whole photosynthetic process.
光合作用是一个过程，其中植物和细菌中的发色团吸收光并将其转化为化学能。为了模拟这个过程，合成了一个发射聚（乙二醇）修饰的四面棱柱形铂（II）笼，并将其用作供体分子在水中构建光捕获系统。选择曙红 Y 作为受体，因为它与金属笼的光谱有很好的重叠，这对于制备光捕获系统是必不可少的。与单独的曙红 Y 相比，这种组合在催化交叉偶联氢析出反应中表现出增强的催化活性。这项研究为利用光捕获系统的输出能量来模拟整个光合作用过程提供了一条途径。
