  非对映异构纯富勒吡咯烷作为光学活性液晶设计的手性平台

  摘要：

  在自组织系统中加入 [60] 富勒烯 (C(60)) 在概念上具有挑战性，但使我们能够获得将凝聚中间相的特性（各向异性、组织）与 C(60)（光和电化学活性）。在这里，我们报告了四种光学活性富勒树枝状聚合物的合成、表征和液晶特性，它们在富勒烯支架和介晶部分之间的连接点是手性的。因此，这项研究的新颖之处在于利用在 C(60) 上的 1,3-偶极环加成反应过程中产生的不对称碳原子，以诱导材料中的介观手性。四种非对映异构富勒吡咯烷 ((R,S)-1、(R,R)-1、(S,R)-1 和 (S, S)-1) 被合成并与第二代向列 (N) 树突结合以产生富勒树枝状聚合物 ((R,S)-2、(R,R)-2、(S,R)-2 和 (S) ,S)-2) 显示手性向列 (N*) 相。立体中心的绝对构型由 X 射线晶体学、1D 和 2D NMR 实验以及圆二色性 (CD) 光谱确定。通过偏光显微镜 (POM) 和差示扫描量热法

• The synthesis and liquid crystal behaviour of monosubstituted ferrocenomesogens
  作者：Christopher Imrie、Christa Loubser、Pieter Engelbrecht、Cedric W McCleland、Yifan Zheng

  DOI：10.1016/s0022-328x(02)02044-2

  日期：2003.1

  The synthesis and characterization of several new series of monosubstituted ferrocenyl-containing liquid crystals has been achieved. The results indicate that a terminal ferrocenyl group can promote stabilization of a nematic liquid crystal state. At least three phenyl rings are required in the molecular core in order to provide nematic properties and addition of a fourth ring substantially enhances it. Bulky lateral substituents or the introduction of linker groups that introduce kinks inhibit liquid crystal phase formation. Short highly polarising terminal groups or terminal groups that support hydrogen bonding support liquid crystal behaviour. (C) 2002 Elsevier Science B.V. All rights reserved.
