  • SUPRAMOLECULAR STRUCTURE HAVING SUB-NANO SCALE ORDERING
    Publication number: 20140142250
    Abstract: An organic crystalline composition is provided. The organic crystalline composition includes a main material having ?-conjugated back bone and a functional group containing an atom having an unshared electron pair, and a linking material combining with the adjacent main material at the functional group by quaternization, organic material-metal interaction, ionic bonding, or hydrogen bonding.

  • Processes of preparing glycolurils and cucurbiturils using microwave
    Patent number: 8293922
    Abstract: Provided are processes of preparing glycolurils and cucurbiturils using the glycolurils by microwave irradiation. Therefore, condensation and cyclization reactions for preparation of industrially widely applied cucurbituril derivatives, oxidation reaction for preparation of hydroxycucurbiturils, and condensation and cyclization reactions between glycolurils and paraformaldehyde or a formaldehyde solution can be efficiently performed in a short time.

  • SUPRAMOLECULAR STRUCTURE OF HAVING SUB-NANO SCALE ORDERING
    Publication number: 20110124820
    Abstract: Provided is a crystalline organic polymer in which a main chain formed of amorphous polymer or monomer having a functional group is combined with a side chain by quaternization, cross-linking, hydrogen bonding or organic material-metal interaction. The main chain material having a functional group is combined with the side chain material to have crystallinity, and the organic polymer having crystallinity exhibits excellent diode characteristics.
