Excited Materials Chemistry Lab
Machine-translated · View original
The lab studies chemistry that uses light and radiation to investigate the excited states of molecules and to control chemical reactions.
AboutAbout the lab
Exploring excited-molecule chemistry with light and radiation.
The Excited Materials Chemistry Lab (Fujitsuka Lab) uses light and radiation to bring molecules into high-energy states and studies the chemical reactions that take place there.
The lab applies light and radiation under spatial and temporal control, and develops chemistry that controls reactions by exploiting the properties of molecules and of the reaction environment.
Its methods include nanosecond-to-femtosecond laser flash photolysis and pulse radiolysis.
The lab is recruiting graduate students for the Department of Applied Chemistry, Graduate School of Engineering, and welcomes lab visits.
Key terms
- excited state
- A state in which a molecule has absorbed energy from light or an electron beam and is at a higher energy than usual
- laser flash photolysis
- A technique in which a short laser pulse is applied and the changes in molecules that occur immediately afterward are followed over time
- photocatalyst
- A substance that drives a chemical reaction when it absorbs light. This lab is working to improve its activity
ResearchResearch themes
Building on excited-molecule chemistry induced by light and radiation under spatial and temporal control, the lab studies chemistry that controls reactions by exploiting the properties of molecules and reaction environments. Its research uses nanosecond-to-femtosecond laser flash photolysis, pulse radiolysis, spatiotemporally resolved single-molecule fluorescence microscopy, and other techniques.
*Illustrative imageChemistry of excited states induced by light and electron beams
The lab irradiates samples with light or electron beams under temporal and spatial control to study the chemistry of highly reactive excited-state molecules and materials. It uses ultrafast spectroscopy to clarify their dynamics and reactivity, and is working toward improving photocatalytic activity based on charge-transfer dynamics.
*Illustrative imageUncovering the mechanisms of life with light and radiation
The lab aims to develop chemical technologies that image and control living systems with light and radiation. It designs and synthesizes photofunctional hybrid molecules and materials, and develops methods for bioimaging and optical manipulation as well as energy-conversion materials, for applied research in the biosciences.
