3-dihydroxypropoxy groups by a single hydroxy group. The influence of these structural variations on the liquid crystalline properties of these new materials was investigated by polarized-light microscopy, differential scanning calorimetry, and X-ray diffraction. These investigation have shown that, by elongation of the lateral chain, a transition from a smectic monolayer structure (SmA1) via a strongly distorted layer
已经合成了由联苯刚性核、每个末端的极性 2,3-二羟基丙氧基和横向位置的额外长烷基链组成的新型双亲分子。这些三元嵌段分子的结构通过改变烷基链的长度和位置、在 2,3-二羟丙基基团之一和刚性核之间引入额外的间隔单元,以及通过取代其中之一而系统地改变。 2,3-二羟基丙氧基由单个羟基组成。通过偏光显微镜、差示扫描量热法和 X 射线衍射研究了这些结构变化对这些新材料液晶特性的影响。这些研究表明,通过侧链的伸长,
