A novel approach toward the construction of multicomponent two-dimensional (2-D) and three-dimensional (3-D) metallosupramolecules is reported. Simply by mixing carboxylate and pyridyl ligands with cis-Pt(PEt(3))(2)(OTf)(2) in a proper ratio, coordination-driven self-assembly occurs, allowing for the selective generation of discrete multicomponent structures via charge separation on the metal centers. Using this method, a variety of 2-D rectangles and 3-D prisms were prepared under mild conditions. Moreover, multicomponent self-assembly can also be achieved by supramolecule-to-supramolecule transformations. The products were characterized by (31)P and (1)H multinuclear NMR spectroscopy, electrospray ionization mass spectrometry, and pulsed-field-gradient spin echo NMR techniques together with computational simulations.
本文报道了一种构建多组分二维（2-D）和三维（3-D）金属超分子的新方法。通过将羧酸酯和吡啶配体与顺式-Pt(PEt(3))(2)(OTf)(2)以适当的比例混合，发生配位驱动的自组装，允许通过金属中心的电荷分离选择性地生成离散的多组分结构。使用这种方法，在温和的条件下制备了各种二维矩形和三维棱柱体。此外，通过超分子到超分子的转化也可以实现多组分自组装。通过（31）P 和（1）H 多核 NMR 光谱、电喷雾电离质谱、脉冲梯度自旋回波 NMR 技术以及计算模拟对产物进行了表征。
