Research topics: Development of Novel Method for Reaction Intermediate Analysis Using Ultrafast Mixing and Ultrafast Spectroscopy

Keyword

Summary: Understanding reaction mechanisms at the molecular level is essential for the development of chemical reactions. In particular, to understand and control multistep reactions involving multiple reactants, it is crucial to disentangle and elucidate the　interconnected elementary processes. However, conventional reaction analysis methods face limitations, including the difficulty of controlling collision-limited reactions involving multiple molecules and the consequently indirect nature of mechanistic discussion. In particular, examples reporting selective real-time analysis of downstream reaction mechanisms remain extremely limited. In this study, I develop a new analytical methodology that enables direct investigation of reaction mechanisms by integrating rapid mixing and spectroscopy.

I have pursued research with the aim of capturing and understanding phenomena that have been difficult to measure by using spectroscopy, often described as the “eyes of science.” My previous work has focused primarily on a variety of photoreactions and photofunctions. In the grant-supported project, I aim to extend the scope of this approach further and develop it into a study that enables flexible and precise analysis of multistep mixing reactions. Although I am currently affiliated with the field of chemistry, I believe that achieving a sustainable society, one of the shared challenges facing humanity in the 21st century, requires research that transcends disciplinary boundaries and is conducted from a broad perspective. In this project, I will build on my strength in laser spectroscopy while also incorporating the perspective of fluid science to pursue research that will reshape our understanding of chemical reactions.
