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.

多组分超分子结构的简便方法:通过电荷分离选择性自组装



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。只需将羧酸盐和吡啶基配体与 cis-Pt(PEt(3))(2)(OTf)(2) 以适当的比例混合,就会发生配位驱动的自组装,从而可以通过电荷选择性生成离散的多组分结构金属中心的分离。利用这种方法,在温和的条件下制备了各种2D矩形和3D棱柱。此外,多组分自组装也可以通过超分子到超分子的转化来实现。通过 (31)P 和 (1)H 多核 NMR 光谱、电喷雾电离质谱、脉冲场梯度自旋回波 NMR 技术以及计算模拟对产物进行了表征。
