  Nanoscale Tectonics:  Self-Assembly, Characterization, and Chemistry of a Novel Class of Organoplatinum Square Macrocycles

  摘要：

  Six nanoscale molecular squares are reported. They are prepared in essentially quantitative yields via spontaneous self-assembly of preprogrammed 90 degrees angular units with diverse bimetallic linear linkers. Characterization was accomplished with multinuclear NMR and, in two cases, via ESI-FTICR mass spectral data. The size of these novel metallomacrocycles range from 3.6 nm (diagonal) and 2.6 nm (side) for the smallest to 4.7 nm (diagonal) and 3.4 nm (side) for the largest as estimated by extensible systematic force field calculations. The molecular squares incorporating alkynyl units as corners are able to complex four Ag+ ions via the pi-tweezer effect.

Furthermore, spectroscopic and computational studies together with a control experiment were conducted, revealing that the degree of cage tension imposed on the excited-state conformational relaxation of TPE moieties resulted in their distinct photophysical properties. The precise control of conformation holds promise as a strategy for understanding the AIE mechanism as well as optimizing

  由于其广泛的应用，具有聚集诱导发射 (AIE) 特性的材料越来越受到关注。AIEgens，如四苯基乙烯单元，在它们的构象变化过程中显示出不同的发射行为。然而，很少探索中间构象的结构-性质关系。在这里，我们表明对 TPE 单元的构象限制会影响激发态的结构弛豫和由此产生的光物理行为。具体而言，通过配位驱动的基于 TPE 的四吡啶供体与长度增加的 Pt(II) 受体的自组装制备了三种不同尺寸的金属笼。虽然金属噬菌体具有相似的支架，但随着其尺寸的增加，它们表现出荧光红移和量子产率衰减的趋势。此外，还进行了光谱和计算研究以及对照实验，揭示了对 TPE 部分的激发态构象弛豫施加的笼张力程度导致了它们独特的光物理特性。构象的精确控制有望作为理解 AIE 机制以及优化超分子配位配合物平台上材料的光物理行为的策略。

Moreover, on account of their AIE characteristics in the condensed state and ability to interact with electron-deficient substrates, the photophysics of these metallacycles is sensitive to the presence of nitroaromatics, motivating their use as sensors.

  组织多个功能活性位点的材料，尤其是那些具有聚集诱导发射 (AIE) 特性的材料，由于其广泛的应用而受到越来越多的关注。尽管早期的架构很有前景，但由于繁琐的共价合成程序通常伴随着这些制备过程，因此在单个实体中制造和制备多个 AIEgens，例如多个四苯基乙烯 (multi-TPE) 单元仍然是一个巨大的挑战。协调驱动的自组装是一种替代合成方法，有可能提供具有发光特性的多 TPE 架构。在这里，我们报告了一个新的离散多 TPE 金属环家族的制备，其中 TPE 单元的两个悬垂苯环作为结构元素保持未使用，代表基于超分子配位复合平台的新型 AIE 活性金属有机材料。这些金属环具有相对较高的摩尔吸收系数，但在稀释条件下荧光发射较弱，因为不受束缚的苯环能够作为非辐射衰变途径进行扭转运动。在分子聚集时，多 TPE 金属环表现出 AIE 活性，量子产率显着提高。此外，由于它们在缩合状态下的 AIE 特性和与

  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 the formation of a series of chiral metallacydes and metallacages by the use of a BINOL-derived dicarbox-ylate as a donor that is capable of affording a variety of coordination angles between its two Lewis basic sites. Two squares, two rhomboids, two tetragonal prisms, and one hexagonal prism were successfully formed when the chiral dicarboxylate donor self-assembled with one of four ditopic Pt(II) complexes, including two bimetallic 180 degrees Pt-based acceptors, a 120 degrees bimetallic Pt-based acceptor, and a 90 degrees mononuclear Ptbased acceptor. Their structures were well characterized by P-31H-1} NMR, ESI-MS, CD, and optical rotation analyses.
