  摘要：

  铁电液晶中的线性电光响应可以通过无阈值开关实现。迄今为止，尚未明确能够产生无阈值响应的铁电液晶的分子设计参数。在本文中，我们探讨了在控制开关过程中可能利用的一些化学设计特征，并建立了性质与结构的相关性，以实现展现无阈值行为的材料。

  含硅多亲弯曲核分子：纳米偏析对于非手性分子形成的液晶相中手性和极性顺序发展的重要性

  摘要：

  合成了由弯曲的芳香核、低聚（硅氧烷）单元和烷基链段组成的多亲分子，并研究了这些分子的自组织。大多数材料组织成极性近晶液晶相。这些中间相的转换过程从非甲硅烷化化合物的反铁电通过超顺电转变为表面稳定的铁电，随着甲硅烷化链段的分离增加。提出硅氧烷亚层稳定极性向斜铁电（SmC（s）P（F））结构，并且从宏观极性顺序以及空间效应的逃逸导致层变形，形成无序微畴，产生光学各向同性。另一个显着特征是具有相反旋向性的手性域的自发形成。对于两种化合物，发现这些域的旋光度随温度而变化，这与分子倾角从 < 45 度增加到 > 50 度有关。这一观察证实了最近提出的层光学手性概念（Hough, LE; Clark, NA Phys. Rev. Lett. 2005, 95, 107802），这是超分子系统中光学活动的新来源。随着烷基链长度的增加，偏析消失并且发现从近晶相到柱状相的转变。在柱状相中，转换过程是反铁电的

• Induction of Smectic Layering in Nematic Liquid Crystals Using Immiscible Components. 1. Laterally Attached Side-Chain Liquid Crystalline Poly(norbornene)s and Their Low Molar Mass Analogs with Hydrocarbon/Fluorocarbon Substituents

  contrast to their hydrocarbon analogues which exhibit only nematic mesophases, poly5-[[[2‘,5‘-bis[(4‘‘-(n-(dimethylsiloxyl)alkoxy)benzoyl)oxy]benzyl]oxy]carbonyl]bicyclo[2.2.1]hept-2-ene}s and their low-molar-mass model compounds exhibit smectic C mesophases. Since nematic liquid crystals can be forced into layers by terminating their hydrocarbon substituents not only with fluorocarbon segments but also

  与仅表现出向列中间相的烃类似物相比，聚5-[[[[2',5'-双[(4''-(n-(二甲基甲硅烷氧基)烷氧基)苯甲酰基)氧基]苄基]氧基]羰基]双环[2.2.1]hept-2-ene}及其低摩尔质量模型化合物表现出近晶C中间相。由于向列液晶可以通过不仅用碳氟化合物链段而且用柔性硅氧烷链段终止它们的烃取代基而被迫成层，这支持了这样的假设，即含有线性碳氟化合物链段的两亲分子的近晶介晶主要是由于碳氢化合物的不混溶性和碳氟化合物段，而不是“介晶全氟烷基棒”的形状持久性。2、5-双[(4'-(n-(低聚二甲基甲硅烷氧基)烷氧基)苯甲酰基)氧基]甲苯模拟聚合物形成的相和它们转变的一般温度，因此是聚合物的极好模型。5-[[2',5'-双[(4''-(n-(低聚二甲基甲硅烷氧基)烷氧基)苯甲酰基)氧基]苄基]氧基]...

Poly(methylsiloxanes) and poly(methyl-co-dimethylsiloxanes) with side chains containing 4-alkoxybenzoic acid pendant groups attached through aliphatic spacers were synthesized for use as H-bond donor polymers. trans-4[(4-Metho

• Influence of Interim Alkyl Chain Length on Phase Transitions and Wide-Band Reflective Behaviors of Side-Chain Liquid Crystalline Elastomers with Binaphthalene Crosslinkings

  A series of side-chain polysiloxane liquid crystalline elastomers, E-Cm (where m is the number of carbon atoms in the interim alkyl groups, and m = 4, 6, 8, 10), with binaphthalene derivatives as crosslinkings, were designed and synthesized. The mesophase structures of these elastomers were dependent on the value of m. The elastomers with m <= 8 could form cholesteric (Ch) phases, while both smectic A and Ch phases could be formed for the elastomer with m = 10. Blue phases can be achieved when m >= 8. Besides, the helical twisting power (HTP) of all the elastomers exhibits a turning point with changing temperature. Both the turning temperature and HTP have an apparent dependence on the value of m. By adjusting the interim alkyl chain length in the elastomers, both visible and near-infrared light wide-band reflective films can be obtained. The broadband reflection mechanism was confirmed by SEM investigations.
• Induction of Smectic Layering in Nematic Liquid Crystals Using Immiscible Components. 5. Laterally Attached Side-Chain Liquid Crystalline Poly(norbornene)s and Their Low Molar Mass Model Compounds with Short Fluorocarbon Segments

  5-[[[2',5'-Bis[(4"-n-((perfluoroalkyl)alkoxy)benzoyl)oxy]benzyl]oxy]carbonyl]bicyclo[2.2.1]hept-2-enes with short fluorocarbon segments were polymerized by ring-opening metathesis polymerization in THF at room temperature using Mo(CHCMe2Ph)(N-2,6-'Pr2Ph)(O'Bu)(2) as the initiator. Although hydrocarbon and fluorocarbon segments as short as three methylenic units each induce smectic layering in the corresponding 2,5-bis[4'-(n-(perfluoroalkyl)alkoxy)benzoyl]oxy}toluene model compounds, the polymers require at least eight and three, or five and four methylenic units in the hydrocarbon and fluorocarbon segments, respectively, to organize into smectic layers; polymers with shorter hydrocarbon and/or fluorocarbon segments are nematic.
