| 摘 要： | 本文报道三种含芳酯的二氮杂-18-冠-6的合成。它们显示出向列型液晶的特性。探讨了分子结构对液晶性质的影响。冠醚液晶7在无机盐掺杂后是否仍有液晶性质与掺杂的无机盐阴离子的结构有关, 而与阳离子的种类无关。无机盐掺杂量对液晶清亮的影响也作了研究。

Synthesis and properties of nematic liquid crystal compounds containing diaza-18-crown-6 ether unit |

| Abstract: | Three aryl esters containing diaza-18-crown-6 units (I, II and III), were synthesized and shown to display nematic liquid crystalline properties. The effect of the mol. structure on liquid crystalline properties was studied. Whether crown-ether liquid crystal II doped with inorganic salt would display liquid crystalline properties depend upon the structure of the anions, regardless of the nature of the cations. The effect of the amount of doping inorganic salt on the clear point was also studied. |
