Organic Functional Chemistry Lab
Machine-translated · View original
A lab that creates new π-electron molecular systems that do not use benzene.

AboutAbout the lab
Opening up a world of molecules no one has yet known
The Organic Functional Chemistry Lab (Fukazawa Lab) aims to create organic materials with excellent optical and electronic functions, and conducts comprehensive research from molecular design to the development of synthetic methods and the elucidation of physical properties.
The lab designs and synthesizes, from its own original ideas, new π-conjugated molecules with unusual structures and modes of electronic conjugation. It then feeds their properties and functions back into the rational molecular design of photofunctional materials, aiming to advance fundamental organic chemistry and materials science.
Key terms
- π-conjugated compound
- A compound in which π electrons are delocalized across the whole molecule. It can serve as a material that makes use of optical and electrical properties
- Non-benzenoid
- Meaning not based on a benzene ring. Non-benzenoid π-conjugated compounds are a treasure trove of optical and electronic functions
- Ring fusion
- Rings joining together by sharing a bond
ResearchResearch themes
Aiming for properties and functions that cannot be achieved with existing frameworks such as benzene, the lab focuses on non-benzenoid π-conjugated compounds.
*Illustrative imageDeveloping ideal stabilization methods
Non-benzenoid π-conjugated compounds are reactive and fragile molecules. The lab has shown a way to stabilize them while preserving their characteristic electronic structures, by fusing on heteroaromatic rings with weak aromaticity or polycyclic aromatic frameworks.
*Illustrative imageMolecular design that brings out distinctive properties
The lab designs and creates new molecules that overturn conventional wisdom, such as electron acceptors without electron-withdrawing groups and stable molecular materials with extremely small band gaps. It is also developing substituents that control how molecules are arranged.
*Illustrative imageDeveloping practical synthetic methods
Synthetic methods for non-benzenoid π-conjugated compounds are largely unexplored. The lab is working to establish methods that can make compounds that could not be synthesized before, that withstand practical scales, and that allow the structure to be diversified late in the synthesis.
