Research Interests

Organic solid-state chemistry offers avenues for unique functional properties and fascinating molecular structures. Of particular interest are crystalline organic materials that are bound exclusively by the weakest intermolecular interactions—London dispersion forces. By precisely controlling these weak interactions and combining multiple molecules within one crystalline entity, it should be possible to create materials with intriguing material properties. Such investigations will also expand the concept of organic crystal towards doped-organic crystalline materials—a class of materials already of interest for medicines but also holds significance for materials science.

Background and Motivation

There is still much to be discovered in the realm of crystalline organic materials. The versatility of organic materials offers a new dimension to organic crystals, presenting opportunities to create a single crystal composed of two or more different organic molecules. Our aim is to utilize this versatility to develop novel organic crystals for use as functional materials.
