  Alkali cation induced liquid crystalline properties of an oligophenylenevinylene-benzocrown ether conjugate

  摘要：

  An oligophenylenevinylene-benzocrown ether conjugate has been prepared and its binding selectivity for alkali metal ions evaluated by electrospray mass spectrometry. Whereas this benzocrown-ether derivative does not exhibit any liquid crystalline properties, the self-assembly by coordination to potassium or cesium leads to supramolecular sandwich complexes with mesomorphic properties.

  columnar liquid crystal (LC) structure, owing to the compensation of free spaces between conjugated arms by dimer formation. The void is filled also by up to three anthracene carboxylic acids as guests forming hydrogen bonded supermesogens assembling in columnar LC and soft‐crystal phases. Thin film fluorescence and solid‐state NMR spectroscopy imply a transition from a disordered columnar LC to an unexpected

  六取代的C 3合成了具有三个细长的形状持久的低聚（亚苯基亚乙烯基）臂和三个吡啶基氢键受体的对称苯。由于通过二聚体形成补偿了共轭臂之间的自由空间，这些液晶元以双螺旋柱状液晶（LC）的结构进行组装。该空隙也被多达三种蒽羧酸填充，形成柱状LC和软晶相中形成氢键结合的超介元。薄膜荧光和固态NMR光谱意味着从无序的柱状LC过渡到填充的软柱状晶相的出乎意料的双重纳米分离形态。蒽和低聚（亚苯基亚乙烯基）生色团在柱内发生另外的分离，不同于LC结构中脂肪族和芳香族结构单元的一般隔离。新型的超介基因将使合理设计带有多种不同共轭构件的主客体双电缆。
