Outline of Final Research Achievements

Precise control of molecular arrangements in solid state materials is getting important due to recent development of organic devices. To date, the arrangement design has been conducted based on computational calculation and the supramolecular synthon approach. However, it still remain difficult to control the arrangements precisely. In this study, we applied a high-ordered supramolecular synthon composed of 4,4’-dicarboxy-o-terphenyl moiety to construct supramolecular architectures possessing both well-designed structures and spaces. We constructed porous layered materials constructed by lamination of a two-dimensionally networked low density sheet composed of a C3-symmetric pi-conjugated planar or bowl-shaped molecules. We also achieved significantly robust porous frameworks, which retain not only permanent porosity but single-crystallinity after activation, enabling precise structural characterization and property evaluation on a single crystal.
