| Outline of Final Research Achievements |
We have found that 2,2-indandicarboxamides assembled into the robust 2D-sheet structures based on formation of eight hydrogen bonds per molecule in the solid state. These sheet structures densely stack on one another in an interdigitated manner, therefore, any cavities, in which guests could be included, were formed among these sheets. In this work, we prepared chiral ring-fused malonamides, such as binaphthalene-fused malonamides, to create inclusion crystals with chiral inclusion cavities among these sheets by biasing the conformational chirality of the malonamide moiety toward either one, and by regulating possible hydrogen-bonding patterns. We found that the substituents at the 3,3’-position of the binaphthalene moiety effect on the conformational chirality of malonamide moiety and change the assembling dimensionality from 2D-sheet to 1D-helical structures. Furthermore, we also prepared pi-bridged bis(malonamide)s to construct hydrogen-bonded pillared-layer porous frameworks.
