“Beam-induced molecular chemistry” based on photo- and radiation-induced chemistry of organic compounds has been investigated from both basic and beam-functional points of view. The research topics are underway with respect to developments of new beam-controlled chemistry, new synthetic chemistry, and new molecular devices and functional materials including photofunctional surface and biomolecular systems.

Our main subject is the development of novel molecule-based materials with promising electronic and photoelectronic properties for organic and molecular electronics. The research is based on the elucidation of the relationship between molecular structures and physical properties to control and improve the functions. We conduct integrated research: molecular design/synthesis, physical/chemical properties, and application to electronic devices such as organic field-effect transistor (OFET), organic solar cells (OSC), and single-molecule electronics.

In this course, we are engaged in research on “Chemistry of Excited-State Chirality and Intermolecular Interactions.” This study represents an integrated experimental and theoretical approach grounded in the principles of physical organic chemistry. The primary objectives of this research are twofold: (1) to elucidate the fundamental nature of molecular chirality and its application in the development of novel chiral luminescent materials, and (2) to construct chiral photoreaction systems predicated on a new paradigm of excited-state control, thereby advancing the field of excited-state chirality and intermolecular interactions.
