英文摘要 | The crystal structure and liquid crystalline properties of a biphenyl-containing acetylene, [5-[(4'-heptoxy-4- biphenylyl) carbonyloxy]-1-pentyne (A3EO7) were investigated by electron crystallography, X-ray diffraction, polarizing optical microscopy, differential scanning calorimetry, transmission electron microscopy, and atomic force microscopy. A3EO7 crystals obtained from a toluene solution adopts a monoclinic P112/m space group with unit cell parameters of a = 6.25 Angstrom, b = 7.82 Angstrom, c = 46.70 Angstrom and gamma = 96.7degrees, as determined using electron diffraction. Upon cooling from the isotropic phase, A3EO7 exhibits a smectic A phase in the temperature range 72.4 - 53.6degreesC. Further lowering of the temperature results in the formation of a smectic C phase which exhibits a strong tendency towards crystallization. |
