Research

"Main group elements" and "π-electrons" are both crucial to the functionality of molecular materials. Despite the recent demand for innovative functional materials, their high potential has not been fully utilized in the field of materials science. While systems with multiple sources of functionality have been developed, these systems often operate independently or only supplement the primary function, failing to produce significant innovations.

Our research aims to explore the unexplored electronic states, physical properties, and reactivity that arise from the synergy between main group elements and π-electrons. Through this research, we seek to contribute to the creation of innovative functional materials that will benefit society in the future and establish design guidelines for these materials.
