Four derivatives of hexakis(4-alkoxybenzoyloxy)triphenylene, for which peripheral phenylene groups are fluorinated at the inner and the outer positions were studied for their mesomorphic behaviour to reveal that the alteration of fluorinated positions in the phenyl rings leads to a drastic change of the mesomorphism involving the thermal stability.
研究了四种六(4-烷氧基苯甲酰氧基)三亚苯的衍生物,这些衍生物的外围亚苯基基团在内部和外部位置被氟化,研究结果表明,改变苯基环中的氟化位置会导致涉及热稳定性的中间形态发生急剧变化。
