| Outline of Final Research Achievements |
Intrinsically chiral molecules have attracted much attention for asymmetric catalysts and chiral (supra)molecular architecture. The electronic CD are quite sensitive spectroscopic method to attain information on three-dimensional molecular structure through the angular correlations between electric and magnetic transition moments, with aid of the state-of-the-art ab initio calculations. We designed a fused helicenes, i.e. phenanthrochrysene and dinaphtho[6]helicene, where the electric and magnetic transition dipole moments are aligned in the same direction, by which the rotatory strength in CD spectrum can be significantly augmented. Successful enhancement of Cotton Effects for these fused helicenes may provide us with a new strategy for designing advance chiroptical materials and devices based on helical structure.
