中文摘要:
新奇 carbosilane 液体水晶的 dendrimers 基于 1,6-hexanediol 被准备。用先锋,有 SiCl 的 Gn-Cl (n=13 ) 作为树枝状的脚手架和 4- 在圆周上结合[4-(6-hydroxyhexyloxy ) phenylazo ] 是的硝基苯 mesogenic 组,一系列 carbosilane 液体到第三代的从第一的水晶的 dendrimers 被综合。水晶的 dendrimers 显示出的这些 carbosilane 液体近晶的阶段。
英文摘要:
Novel carbosilane liquid crystalline dendrimers based on 1,6-hexanediol were prepared. Using the precursors Gn-C1 (n = 1-3) with Si-C1 bonds on the periphery as dendritic scaffolds and 4-[4-(6-hydroxyhexyloxy)phenylazo]- nitrobenzene as mesogenic group, a series of carbosilane liquid crystalline dendrimers from the first to the third generation were synthesized. These carbosilane liquid crystalline dendrimers showed smectic phase.
