报告摘要:

  Visible light irradiation covers a range of wavelengths that corresponds to 40-70 kcal/mol of energy. While blue and purple light is most common and enabling, the use of these wavelengths has limitations with respect to substrate scope and material penetration. We have developed a suite of Os-based catalysts that undergo spin forbidden excitation directly to the triplet state in the deep red (DR) and near infrared (NIR) range, facilitating low energy excitation for photoredox catalysis. Catalyst discovery, synthetic applications and biological imaging will be discussed.

报告人简介:

  Tomislav Rovis is currently Samuel Latham Mitchill Professor of Chemistry at Columbia University. Following his undergraduate studies at the University of Toronto, he earned his Ph.D. degree at the same institution (with Prof. Mark Lautens). From 1998–2000, he was an NSERC postdoctoral fellow at Harvard University (with Prof. David A. Evans). In 2000, he began his independent career at Colorado State University and was promoted in 2005 to Associate Professor and in 2008 to Professor and John K. Stille Chair in Chemistry. His group’s accomplishments have been recognized by a number of awards including an NSF CAREER and a Roche Excellence in Chemistry award. He has been named a GSK Scholar, Alfred P. Sloan Fellow, Fellow of AAAS, Alexander von Humboldt Foundation Fellowship, and an Arthur C. Cope Scholar. Since 2024, he serves as an associate editor of JACS.
