Chain change: Variations in the position, number, and chain length of the n‐alkoxy chains readily tune the liquid‐crystalline properties of 2,5‐diaryl‐1,3,4‐thiadiazole derivatives from smectic to hexagonal columnar mesophases at room temperature. The calamitic S‐heterocyclic compounds show electrical conductivity in both solid and liquid‐crystal states.
链变化:在室温下,正烷氧基链的位置,数量和链长的变化可轻松调节2,5-二芳基-1,3,4-噻二唑衍生物的液晶性质,从近晶到六方柱状中间相。cal族S杂环化合物在固态和液晶态下均显示出导电性。
