主講人介紹：
北京大學學士畢業后（2009，林建華教授，李國寶副教授）在美國北卡羅萊那大學教堂山分校獲得博士學位（2013，林文斌教授），開展MOF催化研究。之后在芝加哥大學開展博士后研究，從事飛秒超快光譜（2013-2015，Greg Engel教授）。2015.07-至今在廈門大學任教授，（中央組織部重要人才計劃青年項目獲得者）。發表論文70余篇，他引7000余次。課題組目前主要研究方向為二維金屬有機單層及以其構筑的人工光合作用系統。
主要內容：
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.
