Turning ideas into form—that’s one of the most compelling aspects of organic chemistry. This field offers both a clear framework for design and a remarkable degree of creative freedom, all grounded in the reality of molecules that materialize. Molecules and reactions follow strict rules, yet the range of combinations and transformations they allow far exceeds what we can easily imagine. In our lab, we explore the full potential of organic chemistry through the design, transformation, and functionalization of molecules—and through the joy of seeing what we imagine become real.
考えたことを，かたちにする――それが有機化学の根源的な魅力のひとつです．設計のしやすさと高い自由度，そしてそれらが実際の“もの”として立ち上がってくる実在性に，この分野ならではの面白さがあります．分子や反応は厳密なルールに従って成り立っていますが，その組み合わせや変換の可能性は，私たちの想像をはるかに超えて広がっていきます．私たちの研究室では，有機分子の設計・変換・機能化を通して，有機化学のそうした醍醐味を追求しています．
