Outline of Final Research Achievements |
In this study, tweezer-type chiral diamines and bisureas were successively obtained in high stereoselectivities by utilizing the double asymmetric addition of diethylzinc to 4,6-dibenzofurandialdehyde. These molecular tweezers exhibited remarkable chiral recognition properties for chiral acids and anions. In addition, the solubilization of single-walled carbon nanotubes in an organic solvent was realized by using an imine polymer obtained from a diundecyl-substituted dibenzofuran-type chiral diamine and an aromatic dialdehyde. Furthermore, the synthesis of a chiral diamine that can exhibit an unprecedented switching of circularly polarized luminescence and the self-assembly of nanometer-ordered macrocyclic hexaimine were also achieved.
