The lab creates the next functional materials from pillar-shaped molecules.
AboutAbout the lab
Designing molecules and assembling them to create function.
The Functional Chemistry Lab (Ogoshi Lab) develops next-generation functional materials by designing molecules and assembling them.
A supramolecule is an ordered assembly of multiple molecules held together by non-covalent forces such as hydrogen bonds.
The lab designs functional molecules with simple, elegant structures and lets them self-assemble to create supramolecules with new functions.
Founded in 2019, the lab aims for truly original research, with students and faculty enjoying experiments and discussion together.
Key terms
- Supramolecule
- An ordered assembly of multiple molecules held together by weak forces such as hydrogen bonds
- Pillar[n]arene
- A pillar-shaped molecule in which benzene rings are linked into a ring. Other molecules can be taken into its internal cavity
- Planar chirality
- A property in which the orientation of a molecule's faces, front or back, creates a distinction like that between a right hand and a left hand

ResearchResearch themes
By designing functional molecules with simple, elegant structures and letting them self-assemble, the lab develops supramolecules that show new functions. Centering on the pillar-shaped macrocycle "pillar[n]arene," it studies the spaces that molecules create, three-dimensional frameworks, phosphorescent materials, and macrocycles containing heteroatoms.

*Illustrative imageThe Birth of Pillar[n]arenes
In 2008, the lab developed a macrocyclic host molecule shaped like a polygonal prism and named it "pillar[n]arene." Depending on the solvent used, pentagonal or hexagonal prisms can be made selectively. With more than 1,700 papers published on it, it is now an important molecule in supramolecular chemistry.
*Illustrative imageSpaces Built from Pillar-Shaped Molecules
Taking advantage of the pillar shape, the lab builds assemblies such as tubes, sheets, and vesicles. By attaching various functional groups to the top and bottom rims, it has produced materials that change shape when they take in gas and temperature-responsive materials that remember their shape.
*Illustrative imageRevisiting Them as π-Conjugated Systems
Pillar[n]arenes are characterized by their symmetric pillar structure and planar chirality. Although this molecule is often handled in host–guest chemistry, the lab examines it as a π-conjugated system, investigating its structure and electronic states, and is finding new aspects of it.
*Illustrative imageCreating Space Outside with Three-Dimensional Frameworks
The lab is developing π-fused propellanes, which have extended π-conjugated systems, as three-dimensional building units. It turns them into network polymers to study gas adsorption, and creates molecules with chiral arrangements that respond differently to left- and right-circularly polarized light.
