22_01/2012Liquid Crystals: Mesomorphic Organization and Thermochromic Luminescence of Dicyanodistyrylbenzene-Based Phasmidic Molecular Disks: Uniaxially Aligned Hexagonal Columnar Liquid Crystals at Room Temperature with Enhanced Fluorescence Emission and Semiconductivity (Adv. Funct. Mater. 1/2012)

(2Z,2'Z)-2,2'-(1,4-phenylene)bis(3-(3,4,5-tris(dodecyloxy)phenyl)acrylonitrile) (GDCS) molecules self-assemble into supramolecular disks consisting of a pair of molecules in a side-by-side dis-position assisted by secondary bonding interactions of the lateral polar cyano group, which, in turn, constitute the hexagonal columnar LC structure. As demonstrated on page 61 by Dongho Kim, Soo Young Park, and co-workers, uniaxially aligned liquid crystal (LC) and crystalline GDCS microwires with enhanced fluorescence and semiconductivity are successfully fabricated by using a micromolding in capillaries (MIMIC) process.
