smectic liquid crystal
解釋
蝶狀液晶-
Smectic liquid crystal
近晶相液晶 -
When liquid crystal ( lc ) is in smectic - a ( sa ) phase, its molecules disperse in layers ( sandwich ) and the molecular long axis tropism is in some order and the director is perpendicular to the layers
液晶近晶a相,分子質心按層狀分佈(有層狀結構) ,分子長軸取向有序,指向矢垂直於層面。用三個序參量, ,描述。 -
2, upon heating to their respective melting temperature, all the compounds above went to liquid crystal phase. the typical chiral smectic c phase lined texture and finger print texture, smectic fan texture and broken fan shaped texture, nematic schlieren texture schlieren texture and ball grandle texture, paramorphosis texture can be observed
實驗結果表明:一,化合物2 、 4 、 16 、 17和18均具有熱致液晶性;二,以上化合物加熱至各自的熔點以上都能形成液晶態,在液晶態可以觀察到新的席夫堿型液晶冠醚的合成與表徵手性近晶c相的層線織構和指紋織構。
