介绍了一种通过多组分、配位驱动、无模板自组装构筑功能化金属超分子四棱柱的新方法。四-（4-吡啶基苯基）乙烯、90° Pt（II）受体和用羟基或胺基、疏水烷基链或电化学活性二茂铁官能化的双位联吡啶或羧酸酯配体的组合在温和条件下产生一套七个自组装的四元棱柱。这些三维金属超分子的特征在于多核NMR（31 P和1H）和质谱。它们的形状和大小是使用MMFF力场模拟建立的。此外，它们的近似尺寸进一步支持PGSE NMR实验。
A new approach for the construction of functionalized metallosupramolecular tetragonal prisms via multi-component, coordination-driven, template-free self-assembly is described. The combination of tetra-(4-pyridylphenyl)ethylene, a 90° Pt(II) acceptor, and ditopic bipyridine or carboxylate ligands functionalized with hydroxyl or amine groups, hydrophobic alkyl chains, or electrochemically-active ferrocene, yields a suite of seven self-assembled tetragonal prisms under mild conditions. These 3-D metallosupramolecules were characterized by multinuclear NMR (31P and 1H) and mass spectrometry. Their shapes and sizes were established using MMFF force-field simulations. In addition, their approximate sizes were further supported by PGSE NMR experiments.
