We present a new strategy for the biomimetic preparation of integrated photoactive complexes consisting of light harvesting and electron separation/transfer components via the hierarchical assembly of porphyrin and platinum nanoparticles on the surface of short-peptide self-assembled structures. The complexes can catalyze the conversion of visible light energy into chemical energy in the absence of an electron mediator and store it as nicotinamide adenine dinucleotide (NADH). This provides a promising step towards artificial photosystems through precisely controlled interactions of light-capturing agents, electron separators and biomolecules.

肽介导的卟啉基层次配合物,用于光化学转化。

我们提出了一种仿生制备一体化光敏复合物的新策略,该复合物由光收集和电子分离/转移组分组成,通过短肽自组装结构表面上的卟啉和铂纳米颗粒的分级组装。在不存在电子介体的情况下,络合物可以催化将可见光能转换为化学能,并将其存储为烟酰胺腺嘌呤二核苷酸(NADH)。通过精确控制光捕获剂,电子分离器和生物分子的相互作用,这为朝着人造光系统迈出了令人鼓舞的一步。
