4-decyloxybenzoyl and 3,4,5-tris(decyloxy)benzoyl groups, are described. Such units are linked to the TTF core through spacers of different lengths. Compound 18b exhibits a metastable discotic mesophase and constitutes the first example of a discotic liquid crystal with a tetrathiafulvalene central core.
描述了四取代的四
硫富富瓦烯7 ab和18 ab的合成和表征,它们带有促生单元,例如4-癸氧基苯甲酰基和3,4,5-三(癸氧基)苯甲酰基。这样的单元通过不同长度的间隔物连接到
TTF芯。化合物18b表现出亚稳态的盘状中间相,并构成具有
四硫富瓦烯中央中心的盘状液晶的第一实例。
