  Self-Assembly of Molecular Dumbbells into Organized Bundles with Tunable Size

  摘要：

  Dumbbell-shaped molecules consisting of three biphenyls connected through vinyl linkages as a conjugated rod segment and aliphatic polyether dendritic wedges with different cross-sections (i.e., dibranch (1), tetrabranch (2) and hexabranch (3)) were synthesized and characterized. The molecular dumbbells self-assemble into discrete bundles that organize into three-dimensional superlattices. Molecule 1, based on a dibranched dendritic wedge, organizes into primitive monoclinic-crystalline and body-centered, tetragonal liquid crystalline structures, while molecules 2 and 3, based on tetra- and hexabranched dendritic wedges, respectively, form only body-centered, tetragonal liquid crystalline structures. X-ray diffraction experiments and density measurements showed that the rod-bundle cross-sectional area decreases with increasing cross-section of the dendritic wedges. The influences of supramolecular structure on the bulk-state optical properties were investigated by measuring the UV/Vis absorption and steady state fluorescence spectroscopies. As the cross-section of the dendritic wedge of the molecule increases, the absorption and emission maxima shift to higher energy. This can be attributed to a quantum size effect of the three-dimensionally confined nanostructure.

  纳米结构的胶束纳米管由水中的二核碱基单体自行组装而成。

  摘要：

  尽管水性两亲性组装体在科学和工业中至关重要，但是由于维持它们的疏水相互作用的非定向性质，这些纳米物体的尺寸和形状通常难以精确控制。在这里，采用了一种受生物启发的策略，该策略包括对具有屏蔽的定向沃森-克里克氢键功能的两亲物进行编程，将其在水中的自组装引向了一种新型的手性胶束纳米管家族，该纳米管具有部分填充的直径约2 nm的亲脂性孔。此外，成功地证明了这些定制的纳米管可提取和容纳大小和化学亲和力互补的分子。

  Self-assembling coordination polymers based on Pd II and Cu II metal ions were prepared from complexation of a bent-shaped bispyridine ligand and a corresponding transition metal. These coordination polymers were observed to self-assemble into supramolecular structures that differ significantly depending on the coordination geometry of the metal center. The polymer based on Pd II self-assembles into

  由Pd II和Cu II金属离子组成的自组装配位聚合物是由弯曲形的双吡啶配体与相应的过渡金属络合制备的。观察到这些配位聚合物自组装成超分子结构，该超分子结构根据金属中心的配位几何形状而显着不同。基于Pd II的聚合物可自组装成层结构，该层结构是通过桥接在金属中心的方形-平面配位几何结构的转位中连接的双吡啶配体形成的。相比之下，基于铜II的聚合物采用双螺旋构型，带有规则的沟槽，由链间氯化铜二聚体相互作用驱动。通过具有芳香族骨架的密度泛函理论的结构优化进一步证实了双链螺旋结构，表明优化的双螺旋结构在能量上是有利的，并且与实验结果一致。这些结果表明弱的金属-配体桥联相互作用可以提供一个有用的策略来构建稳定的双链螺旋纳米管。

  have synthesised a neutral, water‐soluble, PtII complex able to aggregate more efficiently in aqueous solutions than in organic solvents. The aggregates are luminescent and are not quenched by molecular oxygen. Further, we have prepared phosphorescent hydrogels utilising host–guest interactions between cyclodextrins and the tetraethylene glycol tails of the PtII complex. The soft assemblies feature host‐dependent

  我们合成了一种中性，水溶性的Pt II复合物，该复合物在水溶液中的聚集比在有机溶剂中的聚集更有效。聚集体是发光的，不会被分子氧淬灭。此外，我们利用环糊精和Pt II配合物的四甘醇尾巴之间的主体-客体相互作用制备了磷光水凝胶。软装配具有依赖于宿主的发射特性。

  size and shape of these nano‐objects is often difficult to control with accuracy owing to the non‐directional nature of the hydrophobic interactions that sustain them. Here, using a bioinspired strategy that consists of programming an amphiphile with shielded directional Watson–Crick hydrogen‐bonding functions, its self‐assembly in water was guided toward a novel family of chiral micelle nanotubes
