(Kyosei 7) Environmentally Harmonious Organic Synthesis Lab
Machine-translated · View original
The lab uses environmentally harmonious organic synthesis to make luminescent materials and artificial peptides.

AboutAbout the lab
Studying everything from synthesis to function.
The Environmentally Harmonious Organic Synthesis Lab studies how to make functional molecules through organic synthesis that is in harmony with the environment.
Under the motto "research consistently from synthesis to function (application)," the lab investigates both synthetic methods for new substances and the properties those substances show.
It works on reactions that take advantage of elements other than heavy metals, especially iodine and sulfur, and on artificial peptides made from amino acids.
From molecules with extended π-electron systems, the lab designs highly luminescent fluorescent substances and dye materials that absorb light for use.
Key terms
- Supramolecule
- An assembly formed when molecules gather through weak forces. It shows functions that a single molecule does not have.
- π-electron system
- A network of electrons that can move widely within a molecule. It is the basis of the molecule's ability to absorb light and conduct electricity.
- Molecular recognition
- The selective binding of a molecule to a specific partner molecule through its shape and weak interactions.

ResearchResearch themes
The lab regards assembling substances as a form of "synthesis" too, and aims to produce a variety of functional molecules through environmentally harmonious organic synthesis. It believes that developing new structures and reactions leads to substances with functions that have not existed before.
*Illustrative imageEnvironmentally Harmonious Organic Synthesis
With environmental burden in mind, the lab works on organic synthesis that uses elements other than heavy metals, especially the properties of iodine and sulfur. It also studies methods of chemically converting natural amino acids into functional molecules, and methods of building three-dimensional molecular assemblies of π-electron systems and supramolecular compounds by incorporating weak intermolecular forces.
*Illustrative imageArtificial Peptides and Molecular Recognition
Enzymes recognize their partner molecules through weak intermolecular interactions, and this function requires a highly developed three-dimensional structure. Aiming to build such mechanisms artificially, the lab designs amino acid molecules and develops molecular recognition models of enzymes, as well as artificial peptides with helical structures not found in nature.
*Illustrative imageNew Materials with Extended π-Electron Systems
By extending their π-electron systems, organic compounds come to have a variety of optical and electrical properties. By incorporating nitrogen or sulfur, as in pyrrole and thiophene rings, the lab advances the synthesis and property evaluation of efficient fluorescent emitters and dye materials, and also works to clarify the principles by which these properties arise.
