Outline of Final Research Achievements |
Excellent CPL molecules using our original strategy of generating "spatially restricted excitons" using cyclic molecules (cyclodextrins, CyD) were successfully developed. By modifying multiple luminescent groups such as pyrene on the CyD ring, under molecular crowded situation, generating spatially restricted excimers and achieving excellent anisotropy in CPL. Furthermore, the CPL molecules created in this study can utilize their internal space as a recognition site for biomolecules, enabling pioneering CPL sensing of biomolecules.
