| Research Abstract |
The aromatic amide tetramers as spherical molecules are constructed from four benzene rings connected by six amide bonds, and have multiple functionalizable points and asymmetric structures. The spherical molecules were obtained racemic mixtures. Enantiomers were separated by chiral HPLC and related to their CD spectra. In the racemic crystal of the spherical molecule 1, both enantiomeric molecules were arranged in a circle and formed a channel-shaped network structure by weak intermolecular interactions. The channel incorporated water molecules which form 1D chain cluster. Racemic crystal of 2 has also channel-shaped network structure. Otherwise, enantio-pure 2 did not form the channel-shaped structure in the crystal. In addition, complex of spherical molecule 1 or 2 with metal cation formed a different channel-shaped structure in the crystal.
