- 关键词：
- photocatalysis, carbon nitride, organic synthesis, g-CN, UV-vis light, C–H functionalization, sulfurating agent, sustainable chemistry
- 简介：
- The society depends on various organic molecules, which are used as medical drugs, fuels, functional materials, etc. Synthesis of such organic molecules is often energy intensive and laborious. Photocatalysis enables thermodynamically challenging reactions by using energy of electromagnetic radiation in the UV-visible range of the electromagnetic spectrum. In 2010s, graphitic carbon nitride (g-CN), a 200-year-old material, was proved to be an effective photocatalyst to liberate hydrogen from aqueous solutions of electron donors. The motivation for launch of my own research group and establishing the area of research “carbon nitride organic photocatalysis” was: 1) a sincere curiosity to investigate thoroughly g-CN as a photocatalyst in organic synthesis, on the one hand, and 2) the need to create more sustainable methods in organic synthesis on the other. In the past 8 years, the group developed a dozen of organic chemical reactions, which are driven by g-CN photocatalyst upon excitation with UV-vis light. The scope of reactions includes using elemental sulfur as a nearly 100%-atom efficient sulfurating agent, and C–H functionalization of hydrocarbons, among others. Based on these findings, a roadmap was created, which allows designing novel organic chemical reactions that afford target functional molecules.

报告人介绍：
Oleksandr Savateev was born and raised in Kyiv, Ukraine. He received the PhD degree in organic chemistry from the Institute of Organic Chemistry of the National Academy of Science of Ukraine. In 2015, he joined the Max Planck Institute of Colloids and Interfaces in Potsdam, Germany, where he worked as a postdoctoral researcher. In 2017, at the same institute, he started his group “Innovative Heterogeneous Photocatalysis”. In 2023, he took a position of Associate Professor (Vice-Chancellor Early Career Professorship Scheme) at the Chinese University of Hong Kong. His current research interests include organic synthesis mediated by heterogeneous photocatalysts, application of photocharged semiconductors in organic synthesis and data-driven research. In 2024, he completed his Habilitation in Organic Chemistry at the University of Potsdam, Germany. As an educator, he is interested in gamification of teaching and studying. He is a creator of ChemChallenge – the first video game for teaching and studying physical chemistry.
