| Outline of Final Research Achievements |
Electron-donating groups increase pi-electron density by resonance effect. Neutral pi-electron-donating groups, such as dialkylamino groups, have been widely used in various functional molecules to improve the pi-electron density of conjugated systems. In this study, novel substituents that exhibit stronger pi-electron-donating properties than dialkylamino groups were developed. Their synthesis, basic properties, and applicability to functional molecules were investigated.

| Academic Significance and Societal Importance of the Research Achievements |
ジアルキルアミノ基は、蛍光色素や有機分子触媒、配位子などの様々な機能性分子に導入されている。例えば蛍光色素は、生命科学研究において近年盛んに利用されているが、ジアルキルアミノ基の導入によりその吸収及び蛍光波長を長波長化させた有用な蛍光色素がこれまでに数多く開発されている。従って、このような既存の機能性分子に含まれているジアルキルアミノ基を本研究で開発した新規π電子供与基へと置き換えることで、種々の高性能な機能性分子の創成が期待される。
