| Outline of Final Research Achievements |
In this work, we developed successfully optical resolution methods of three kinds of planar chiral [2.2]paracyclophane derivatives in addition to three kinds of planar chiral [2.2]paracyclophanes prepared so far by us. We prepared various enantiopure π-stacked molecules with optically active second-ordered structures by using six kinds of planar chiral [2.2]paracyclophane building blocks. The obtained molecules exhibited excellent circularly polarized luminescence properties with high anisotropy factors. The correlation between orientation of the stacked π-electron systems and the chiroptical properties was elucidated by experimental and theoretical studies. In addition, we succeeded in precision control of size, morphology, and crystal growth direction of skeletal crystals of an organic molecule by crystallization of the enantiopure X-shaped molecule based on the planar chiral [2.2]paracyclophane.
