主要内容:

Energy transfer and light harvesting are important for photocatalysis. The sunlight energy is abundant but diffusive with a typical visible photon density of ~ 1 photon/nm2/ms, leading to a maximum photoelectron generation rate of ~ 1 ms-1 on a single molecular photosensitizer. However, many of the energy storing reactions involves multiple electrons. Green plants use an antenna system with connected chromophore arrays to capture the sunlight energy in a much larger area to support a single reaction centre. Multiple electron/hole injection becomes facile thanks to the light-harvesting network. Two-dimensional metal-organic layers (MOLs) are ideal crystalline models to mimic the light-harvesting system in nature to efficiently transfer energy to reaction centres attached to the 2D film and drive energy gaining reactions. In this talk, I will discuss the synthetic chemistry of MOLs and its functionalization to study photo-driven catalysis.
