  Synthesis and properties of novel liquid crystalline materials with super high birefringence: styrene monomers bearing diacetylenes, naphthyl, and nitrogen-containing groups

  摘要：

  Three new liquid crystal asymmetrical styrene monomers bearing diacetylenes, naphthyl, and nitrogen-containing groups were successfully synthesized from 2-(bromoethynyl)-6-(hexyloxy)naphthalene, 4-(4-bromo-2-vinylphenyl)-2-methylbut-3-yn-2-ol, and derivatives of 4-ethynylaniline. The molecular structures of these compounds were confirmed by FIR, H-1 NMR spectroscopy, elemental analysis, and mass spectrometry. The liquid crystalline properties of monomers were characterized by differential scanning calorimetry and polarized light microscopy. Results indicated that all the compounds exhibited the nematic phase in liquid crystal state and super high optical birefringence of 0.5-0.8. The change of terminal nitrogen-containing group affected the birefringence values in the order of -N(CH3)(2)<-NH2<-NCS. Moreover, measurements using UV-vis and fluorescence spectroscopy showed their good photoluminescence properties and high quantum efficiency of 0.4-1.0. (C) 2009 Elsevier Ltd. All rights reserved.

  diorganopalladium species with favorable stability and an electron-rich nature, leading to efficient sequential reactions with diverse electrophiles and nucleophiles. Specifically, the development of aryl-alkenyl-palladacycle-based transformations could provide an attractive approach with regio- and stereocontrol for the construction of multifunctionalized arylethylenes. However, currently, the C,C-pallada(II)cycle

  五元C , C -钯 (II) 环是一类独特的二有机钯物种，具有良好的稳定性和富电子性，可与不同的亲电子试剂和亲核试剂进行有效的连续反应。具体而言，基于芳基-烯基-钯环的转化的发展可以为构建多功能芳基乙烯提供一种具有区域和立体控制的有吸引力的方法。然而，目前C，C-钯（II）环的形成依赖于骨架中的刚性骨架或空间拥挤来促进环钯化，并且尚未实现没有α-取代基的芳基-烯基-钯环的形成。此外，可以区分两个 sp 的反应这种C (sp 2 )、C (sp 2 )-钯环的2个碳中心仍然难以捉摸。在此，我们报告了一种区域选择性三组分串联烷基化/偶联反应，适用于各种非、α-或 β-取代和 α，β-二取代的邻碘苯基乙烯。富电子 2-吡啶酮配体用于实现环钯化过程，导致芳基-烯基-钯环中间体，其中两个 C-Pd 键因其固有的空间和电子差异而被区分为烷基化。观察到区域/化学选择性和哈米特 σ 值之间良好的线性自由能关系。

  palladium-catalyzed disilylation reaction applicable for a variety of non-, α-, or β-substituted and α,β-disubstituted ortho-halophenylethylenes has been developed. This reaction proceeds with high yields and very low catalyst loadings. The two C–Si bonds of the disilylated products could be well-differentiated chemoselectively in the reaction with various electrophiles.
