| Outline of Final Research Achievements |
There are many reports on planar chiral monosubstituted [2.2]paracyclophanes. Optical resolution method of the monosubstituted [2.2]paracyclophane has already been achieved, whereas there have been limited reports on that of disubstituted [2.2]paracyclophanes. We have developed practical optical resolution method of the disubstituted [2.2]paracyclophanes in order to obtain optically active conjugated polymers based on the planar chiral [2.2]paracyclophane. The obtained [2.2]paracyclophane compounds were readily transformed to give various optically active molecules.
In addition, we have succeeded in the first optical resolution of tetrasubstituted [2.2]paracyclophane. After the optical resolution, we synthesized, for example, optically active propeller-shaped cyclic compound. This compound exhibited intense circularly polarized luminescence by excitation with large dissymmetry factor of 0.013. It is rare that the dissymmetry factor of organic molecules reaches the order of 0.01.
