  3D Interconnected Ionic Nano-Channels Formed in Polymer Films: Self-Organization and Polymerization of Thermotropic Bicontinuous Cubic Liquid Crystals

  摘要：

  Thermotropic bicontinuous cubic (Cub(bi)) liquid-crystalline (LC) compounds based on a polymerizable ammonium moiety complexed with a lithium salt have been designed to obtain lithium ion-conductive all solid polymeric films having 3D interconnected ionic channels. The monomer shows a Cub(bi) phase from -5 to 19 degrees C on heating. The complexes retain the ability to form the Cub(bi) LC phase. They also form hexagonal columnar (Col(h)) LC phases at temperatures higher than those of the Cub(bi) phases. The complex of the monomer and LiBF4 at the molar ratio of 4: 1 exhibits the Cub(bi) and Col(h) phases between -6 to 19 degrees C and 19 to 56 degrees C, respectively, on heating. The Cub(bi) LC structure formed by the complex has been successfully preserved by in situ photopolymerization through UV irradiation in the presence of a photoinitiator. The resultant nanostructured film is optically transparent and free-standing. The X-ray analysis of the film confirms the preservation of the self-assembled nanostructure. The polymer film with the Cub(bi) LC nanostructure exhibits higher ionic conductivities than the polymer films obtained by photopolymerization of the complex in the Col(h) and isotropic phases. It is found that the 3D interconnected ionic channels derived from the Cub(bi) phase function as efficient ion-conductive pathways.

  从假对映体聚集体获得的对映体纳米级结构：通过手性扩增在自组装盘状三嗪三酰胺中形成的螺旋手性的共价固定。

  摘要：

  报道了通过基于中士/士兵原理的手性扩增方法在自组装系统中产生的手性螺旋结构的共价固定。盘状三嗪三酰胺通过中心三苯基三嗪基团之间的pi堆积相互作用，酰胺基团之间的氢键相互作用以及烷基在非极性溶剂（如己烷）中的范德华相互作用而自组装形成柱状螺旋状聚集体，辛烷，甲苯和对二甲苯。当非手性三嗪三酰胺士兵组分与少量的手性三嗪三酰胺中药组分混合时，由军士组分控制自组装士兵组分的固有超分子螺旋性导致手性扩增和仅具有螺旋性的假对映体聚集体的形成。当具有末端烯烃基团的非手性组分在少量的没有烯烃基团的手性组分的存在下形成假对映体聚集体时，可以通过由Grubbs催化剂介导的闭环烯烃复分解聚合来保持螺旋性。在聚合和除去手性组分之后，从非手性士兵组分获得的聚合物结构是光学活性的，因此可以认为是其中保留了从手性中士组分转移的手性信息的对映体。纳米级手性结构完美固定，如在高温低浓度下在极性THF介质中获得的CD光谱证据所示。AFM和TEM观察显示直径为2-4

• A facile route to multi-functionalization of methyl gallate: pivotal synthons for mesomorphic materials

  The preparation of mono-, di- and trisubstituted gallic derivatives is described using either 1-bromododecane or 12-bromo-1-dodecanol. After saponification of the methyl ester bearing the dodecanol groups, subsequent functionalization with methacryloyl chloride provides the hybrid methacrylate esters/anhydride species. Selective cleavage of the anhydride function gives rise to the corresponding acids, which have been further functionalized to the imine derivative 15 by condensation with 4-[imino-4-(toluyl)]phenol. This reaction is made possible using the acidic form of 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide (EDC.HCI) and dimethylaminopyridine (DMAP). Selective hydrolysis of the imine function with a HCl-treated silica provides the targeted aniline in excellent yield. (C) 2002 Elsevier Science Ltd. All rights reserved.

  the achiral triazine triamide soldier component is mixed with a tiny amount of the chiral triazine triamide sergeant component, control of the intrinsic supramolecular helicity of the self-assembled soldier component by the sergeant component leads to chiral amplification and formation of a pseudoenantiomeric aggregate with only one handedness of the helix. The helicity can be preserved by ring-closing
