  通过超分子配位络合物平台的丙氨酸手性金属凝胶：金属凝胶诱导的手性转移

  摘要：

  手性自组装不断引起人们的极大兴趣，因为它们有可能为生物系统和材料科学提供深入的见解。在此，我们报告了使用 Pt(II) ← 吡啶基定向键合方法有效制备基于丙氨酸的手性金属环、菱形 1D 和 1L 以及六边形 2D 和 2L。随后金属环以低浓度组装成纳米球，在氢键、疏水性和π-π相互作用的驱动下产生高浓度的手性金属凝胶。凝胶由具有明确螺旋性的微观手性纳米纤维组成，经圆二色性 (CD) 、扫描 (SEM) 和透射电子 (TEM) 显微镜证实。鉴于这些结果，我们预计这项技术不仅将解锁有趣的新方法来理解自然界的同手性，而且还可以设计包含手性超分子核心的多功能软材料。

  metallacycle was aggregated with heparin through multiple electrostatic interactions, to construct a multi-component hierarchical system. SEM, TEM, and DLS measurements revealed that the photo- and thermal-responsive molecular motor units enabled selective manipulation of the secondary supramolecular aggregation process without dissociating the primary metallacycle structures. These visible-light-responsive

  在超分子组件中组织分子马达以允许运动和集体行动的放大和传输，是迈向未来响应系统的重要一步。金属配位驱动的定向自组装成超分子金属环提供了一种强大的策略，可以将几个运动单元定位在具有明确几何形状的较大结构中。在此，我们提出了一种吡啶基修饰的分子马达配体 (MPY)，它与几何上不同的 di-Pt(II) 受体配合，组装成不同大小和形状的离散金属环。这种协调导致分子马达的吸收带发生红移，使这些机动金属环对可见光做出响应。光化学和热异构化实验表明，金属环中电机的光驱动旋转与溶液中的游离 MPY 相似。CD 研究表明，与旋转循环中每个异构化步骤相关的螺旋度反转都得以保留。为了探索集体运动，通过多重静电相互作用将含有三聚体马达的金属环与肝素聚合，以构建多组分分层系统。SEM、TEM 和 DLS 测量表明，光响应和热响应的分子运动单元能够在不解离初级金属环结构的情况下选择性地操纵二级超分子聚集过程。这些可

  Hierarchical self-assembly centered on metallacyclic scaffolds greatly facilitates the construction of mechanically interlocked structures. The formation of two [3]catenanes and one [4]molecular necklace is presented by utilizing the orthogonality of coordination-driven self-assembly and crown ether-based cryptand/paraquat derivative complexation. The threaded [3]catenanes and [4]molecular necklace were fabricated

  以金属环骨架为中心的分层自组装极大地促进了机械互锁结构的构造。利用配位驱动的自组装和基于冠醚的穴状/百草枯衍生物络合的正交性，提出了两条[3]邻苯二甲酸酯和一条[4]分子项链的形成。分别使用十种和九种总分子组分（分别来自溶液中的四种和三种独特物质）制造了带螺纹的[3] catenanes和[4]分子项链。在所有情况下，都获得了单个超分子集合体，这证明了通过自组装方法实现的高度结构复杂性是可能的。

  The formation of catenated systems can be simplified greatly if one or more rings are generated via self-assembly. Herein we exploit the orthogonality of coordination-driven self-assembly and crown-ether host-guest complexation to obtain a [4]molecular necklace and a [7]molecular necklace based on a well-developed recognition motif of 1,2-bis(pyridinium)ethane/dibenzo[24]crown-8. By adapting the bis(pyridinium)

  如果通过自组装产生一个或多个环，则可以大大简化链状系统的形成。在这里，我们利用协调驱动的自组装和冠醚主客体络合的正交性，获得了基于 1,2-bis(吡啶鎓）乙烷/二苯并[24]冠-8。通过将双（吡啶鎓）基序调整到供体结构单元的骨架中，得到的半刚性双吡啶基物质既可以作为金属环形成的结构元素，也可以作为后续主客体化学反应的位点。供体前体的假线性特性有助于基于所使用的互补受体单元形成三角形和六边形中心金属环。

  The synthesis of a new 120 degrees diplatinum(II) acceptor unit and the self-assembly of a series of two-dimensional metallacyclic polypseudorotaxanes that utilize both metal-ligand and crown ether-dialkyl-ammonium noncovalent interactions are described. Judiciously combining complementary diplatinum(II) acceptors with bispyridyl donor building blocks, with an acceptor and/or donor possessing a pendant dibenzo[24]crown78 (DB24C8) moiety, allows for the formation of three new rhomboidal bis-DB24C8, one new hexagonal tris-DB24C8, and four new hexakis-DB24C8 metallacyclic polygons in quantitative yields. The size and shape of each assembly, as well as the location and stoichiometry of the DB24C8 macrocycle, can be precisely controlled. Each polygon is able to complex two, three, or six dibenzylammonium ions without disrupting the underlying metallacyclic polygons, thus producing eight different poly[2]pseudorotaxanes and demonstrating the utility and scope of this orthogonal self-assembly technique. The assemblies are characterized with one-dimensional multinuclear (H-1 and P-31) and two-dimensional (H-1-H-1 COSY and NOESY) NMR spectroscopy as well as mass spectrometry (ESI-MS). Further analysis of the size and shape of each assembly is obtained through molecular force-field simulations. H-1 NMR titration experiments are used to establish thermodynamic binding constants and poly[2]pseudorotaxane/dibenzylammonium stoichionnetries. Factors influencing the efficiency of poly[2]pseudorotaxane formation are discussed.

  We present a general strategy for the synthesis of stable, multicomponent fused polygon complexes in which coordination-driven self-assembly allows for single supramolecular species to be formed from multicomponent self-assembly and the shape of the obtained polygons can be controlled simply by changing the ratio of individual components. The compounds have been characterized by multinuclear NMR spectroscopy and electrospray ionization mass spectrometry.
