Organoelement Chemistry Lab
Machine-translated · View original
A lab that uses a wide range of elements to create new synthetic reactions and materials.

AboutAbout the lab
Harnessing each element's unique character to create new reactions
The Organoelement Chemistry Lab combines organic compounds with elements such as silicon, boron, and phosphorus, as well as transition metals, to develop new synthetic reactions, functional materials, and catalysts.
The lab has developed methods for synthesizing organoboron and organosilicon compounds using copper(I) catalysts, and also designs catalysts using quantum chemical calculations.
It also works on mechanochemical synthesis, in which reactions proceed in a ball mill without solvents, and on molecular crystals whose emission color changes in response to stimuli.
The lab also conducts many joint research projects with companies and universities in Japan and abroad.
Key terms
- Catalyst
- A substance that makes a reaction proceed more easily without being changed itself. A small amount can change how a reaction proceeds.
- Mechanochemical synthesis
- A method of driving chemical reactions with mechanical force, such as that of a ball mill, without using solvents.
- Mechanochromism
- The property of changing color, or emission color, when force such as rubbing is applied.

ResearchResearch themes
The lab aims to combine organic compounds with other elements to create new and useful synthetic reactions, functional materials, and catalysts. By bringing new ways of thinking into organic chemistry, it aims to create entirely new research fields.
*Illustrative imageSynthesis of Organoboron and Organosilicon Compounds
The lab is developing methods that use copper(I) catalysts to selectively synthesize either organoboron or organosilicon compounds. It also designs chiral copper catalysts using quantum chemical calculations.
*Illustrative imageOrganic Synthesis in a Ball Mill
The lab studies mechanochemical synthesis, in which the mechanical force of a ball mill drives reactions without organic solvents. It has succeeded in achieving selective reactions that proceed only in the solid state and in transforming insoluble compounds.
*Illustrative imageCrystals with Moving Molecules
The lab designs and synthesizes functional molecules and grows crystals in which they are arranged. It discovered mechanochromism, in which the emission color changes when the crystal is rubbed, and also studies crystals that jump in response to stimuli and molecular rotors, in which molecules rotate inside the crystal.
