  Liquid Crystalline Octopus: An Alternative Class of Mesomorphic Dendrimers

  摘要：

  The synthesis and the mesomorphic properties of a new series of liquid crystalline dendrimers, referred thereafter as to octopus dendrimers owing to their eight sidearms, are reported. In these dendritic systems, the arborescence is constituted of mesogenic segments and aliphatic spacers, and as such they differ quite substantially from the classical end-functionalized dendrimers whose dentritic core is more flexible. Such a molecular design was adopted in order for the internal mesogenic segments-constituting the skeleton of the dendrimer-to participate at every level of the molecular organization within the mesophases. The dendritic branches, prepared by a mixed convergent/divergent method, were attached to a tetrapodant central core to yield second generation dendrimers via amido linkage. X-ray diffraction studies showed that the acidic dendron precursors and the final dendrimers exhibit a hexagonal columnar mesophase, whose mesophase stability was found to depend on the number and position of the terminal alkoxy chains. The high density of aliphatic chains imposes curved interfaces at all hierarchical levels of the dendrimers, i.e., between the pro-mesogenic units, the aliphatic spacers, and the terminal chains, forcing the molecules to adopt a wedgelike conformation, promoting the self-assembling toward a supramolecular columnar organization. Because of their original molecular structure, the internal columnar "hard" core of the columns is compatible with an onion-type structure, i.e., made up of successive, concentric crowns occupied by aromatic and aliphatic constituents, as deduced from the analysis of the X-ray diffraction data.

  Proquinoidal DAD 和 ADA 四极发色团的双光子吸收特性

  摘要：

  我们报告了一系列具有原醌型 π 芳族受体的四极分子的合成、单光子和双光子吸收光谱、荧光和电化学特性。这些四极分子具有供体-受体-供体 (DAD) 或受体-供体-受体 (ADA) 电子基序，并具有4- N , N-二己基氨基苯基、4-十二烷氧基苯基、4-( N , N-二己基氨基)苯并[ c ][1,2,5] 噻二唑基或 2,5-二辛氧基苯基电子供体部分和苯并[ c ][1,2,5] 噻二唑 (BTD) 或 6,7-双 (3',7'-二甲基辛基) [1,2,5]噻二唑并[3,4- g]喹喔啉 (TDQ) 电子受体单元。这些共轭结构在非极性溶剂中具有高发射率，并且相对于包含亚苯基组分代替 BTD 和 TDQ 部分的类似参考化合物，它们各自的最低能量吸收带显示出较大的光谱红移。基于 BTD 的 DAD 和 ADA 发色团表现出增加的荧光发射红移，并伴随着荧光量子产率 (Φ f) 随着溶剂极性的增

• Alkoxy-Substituted Hexastyrylbenzenes
  作者：Herbert Meier、Hans Christof Holst

  DOI：10.1002/adsc.200303030

  日期：2003.8

  Star-shaped compounds 2a–e with a central benzene ring and six p-substituted, (E)-configured styryl groups have been prepared by a sequence of three-fold Heck and three-fold Wittig–Horner reactions. Alkoxy chains (OC3H7, OC6H13, OC10H21, OC12H25) on all six arms guarantee a good solubility of 2a–d, whereas the alternating hexyloxy and cyano substitution in 2e leads to an almost insoluble push-pull

  通过一系列三倍的Heck反应和三倍的Wittig-Horner反应，制备了带有中心苯环和六个p取代，（E）构型的苯乙烯基的星形化合物2a–e。六个臂上的烷氧基链（OC 3 H 7，OC 6 H 13，OC 10 H 21，OC 12 H 25）确保2a–d的良好溶解性，而在2e中交替的己氧基和氰基取代导致几乎不溶推挽系统。辐射到2a–d的长波吸收中（λ最大值为341–342 nm）会导致统计上的光交联，其特征是所有二苯乙烯生色团完全降解。

• Synthesis and Liquid Crystal Properties of New Fluorinated Isoxazoles
  作者：L. D. Lopes、A. A. Merlo

  DOI：10.1080/15421406.2015.1030972

  日期：2015.5.3

  New fluorinated LC 3,5-diarylisoxazolines and 3,5-diarylisoxazoles have been synthesized and their thermal properties reported. Isoxazolines were synthesized using [3+2] 1,3-dipolar cycloaddition from nitrile oxide and alkenes with subsequent MnO2-oxidation yielded the corresponding isoxazoles. The title compounds obtained were characterized by H-1 and C-13 NMR, differential scanning calorimetry (DSC), elemental analysis and polarized optical microscopy (POM). The final compounds are composed by terminal flexible hydrogenated alkyl chains or semiperfluoroalkyl chains. 3,5-diarylisoxazoline composed of alkyl chains is not LC, whereas when composed of one or two semiperfluoroalkyl chains it displays SmA mesophase. For 3,5-diarylisoxazoles a second mesophase SmC was also observed.
