  Synthesis and properties of naphthalene trimers linked by 1,3,4-oxadiazole spacers

  摘要：

  Two types of naphthalene trimers linked by 1,3,4-oxadiazole spacers were synthesized and investigated for their physical and electronic properties. 2,6- and 2,7-isomers on central naphthalene moieties were obtained in the forms of pale yellow solids and colorless crystals, respectively. The melting point of the 2,6-isomer was higher than that of the 2,7-isomer. An X-ray crystallographic analysis revealed a pi-stacked column with a short intermolecular distance in the crystals of the 2,6-isomer. The absorption maximum of the 2,6-isomer was red-shifted as compared to that of the 2,7-isomer, indicating a pi-conjugation between di-2-naphthyloxadiazole moieties in the 2,6-isomer. The quantum yields of the 2,6- and 2,7-isomers were measured to be 0.97 and 0.74, relative to that of 2.5-di-2-naphthyl-1.3,4-oxadiazole (0.85). Molecular orbital (MC) calculations demonstrated that the 2,6-isomer had a higher electron affinity than the 2,7-isomer. Thus, the crosslinking of building blocks is important for the design of functional materials. (C) 2008 Elsevier Ltd. All rights reserved.

  利用疏水效应合成分子结和链接的策略

  摘要：

  合成分子结和链接的常规方法主要依赖于金属模板。我们在这里提出了一种替代策略，该策略使用疏水效应来驱动水中复杂互锁结构的形成。我们设计了一个可以产生结和链接的水性动态组合系统。在这个系统中，拓扑复杂的大环的自组装只有在其所有组分的最佳填充最小化与水接触的疏水表面积时才在热力学上有利。因此，可以利用初始构建块的大小、几何形状和刚度来控制特定拓扑的形成。我们通过合成一个 Hopf 链接、一个 Solomon 链接和一个三叶结来说明这个概念的有效性。后一种分子，其自组装由卤化物模板化，在水中以高亲和力结合碘化物。总的来说，这项工作为拓扑复杂分子的合成带来了新的视角：可以有意利用疏溶剂效应来指导节点和链接的高效和选择性自组装。

  A rapid screening method based on traveling‐wave ion‐mobility spectrometry (TWIMS) combined with tandem mass spectrometry provides insight into the topology of interlocked and knotted molecules, even when they exist in complex mixtures, such as interconverting dynamic combinatorial libraries. A TWIMS characterization of structure‐indicative fragments generated by collision‐induced dissociation (CID)

  一种基于行波离子迁移谱（TWIMS）结合串联质谱的快速筛选方法，即使在复杂的混合物中（例如相互转换的动态组合库），也可以深入了解互锁和打结的分子的拓扑结构。通过碰撞诱导解离（CID）生成的结构指示片段的TWIMS表征以及基于母离子和碎片离子到达时间定义的松散参数提供了直接的拓扑识别。为了证明其广泛的适用性，此方法在此处应用于六个Hopf和两个Solomon链接，一个三叶形结和一个[3]链接。

  A novel method for preparing a thermosetting imide resin composition which consists of chemically reacting a liquid mixture of a vinylidene -terminated polybutadiene/ acrylonitrile (VTBN) and a co-reactant comprising a. at least one N,N'-bisimide of an unsaturated carboxylic acid of general formula I wherein B represents a divalent radical containing a carbon-carbon double bond and A represents a divalent radical having at least two carbon atoms, or b. the amide resin reaction product of at least one N,N'-bisimide of general formula I and at least one primary organic diamine or organic hydrazide, or c. the imide resin reaction product of at least one N,N'-bisimide of general formula I, at least one monoimide, and at least one organic hydrazide, to yield a thermosetting imide resin composition containing copolymerised VTBN and co-reactant. A resin composition prepared by this method may be cured at a temperature between 100°C and 350°C to yield a fully cross-linked polyimide matrix containing a dispersion of phase-separated solid particles of copolymerised VTBN and co-reactant.
