| 中文摘要 | 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. |
