Metals and ceramics have been synthesized since prehistoric ages and now constitute the basis of modern electronics, optics and green energy applications.

However, structural diversity of these solid-state materials is much limited compared to organic molecules which e.g. our bodies are comprised of.

We aim at breaking such barriers in chemical space of chalcogenides through low-temperature & stepwise syntheses, advanced characterisation of complex nanostructures and new theoretical frameworks.

Cut & Connect

Functionalities of materials arise from their structures, and thereby it is an ultimate dream for chemists to manipulate arrangements of the constituent atoms precisely as desired. Thousands of different enzymes in our body can cut or connect specifically targeted chemical bonds, and so do the modern genome-editing technology and coupling reactions in organic chemistry, enabling tailor-made design of complex molecular structures with superior functionalities. Then, how about inorganic solid-state materials? Is such a chemical bond editing possible for minerals, ceramics and metals without destructing their overall crystal structures? We have recently proposed to make use of redox-active chalcogen-chalcogen bonds in solids for constructing 2D layers or for triggering deintercalation of bulky chalcogen anions. This discovery made us embark in exploration of new functional materials utilizing this new toolbox for chemical bond editing – i.e. cutting & connecting only targeted anionic covalent bonds without altering other moieties.
