  Liquid crystalline polyamines containing side dendrons: Toward the building of ion channels based on polyamines

  摘要：

  In this article, we modified poly[2-(aziridin-1-yl)ethanol] (PAZE) with the dendron 3,4,5-tris[4-(n-dodecan-1-yloxy)benzyloxy]benzoic acid, to obtain liquid crystalline columnar polyamines. The chemical modification reaction was first tuned on a model compound, N,N-dimethyl-2-hydroxyethylamine. The best results were obtained by the esterification method with N,N'-dicyclohexylcarbodiimide at room temperature, in the presence of 4-dimethylaminopyridine. The obtained copolymers showed higher char yield than starting FAZE. In all cases they exhibited small crystalline portions after annealing and columnar mesophases, as inferred by DSC, XRD and POM. The dimension of the unit cell resulted slightly narrower than in the case of the copolyethers bearing the same dendron. This is probably due to the presence of a longer spacer in PAZE, which allows better accommodating of the side tapered group. (C) 2013 Elsevier Ltd. All rights reserved.

  作者：Daigo Miyajima、Fumito Araoka、Hideo Takezoe、Jungeun Kim、Kenichi Kato、Masaki Takata、Takuzo Aida

  DOI：10.1002/anie.201102472

  日期：2011.8.16

  Current events: An electric‐field‐responsive handle (see picture) was developed that enables large‐area and millimeter‐thick unidirectional orientation of columnarly assembled π‐conjugated liquid‐crystalline molecules. The handles in the columns are hydrogen‐bonded and align along the direction of an applied electric field.

  时事：开发了一种电场响应手柄（参见图片），该手柄能够使大面积和毫米厚度的圆柱状组装的π共轭液晶分子单向定向。列中的手柄是氢键的，并沿着施加的电场方向对齐。
