Abstract

A new approach for the construction of functionalized metallosupramolecular tetragonal prisms via multicomponent, 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 three-dimensional metallosupramolecules were characterized by multinuclear NMR ((31)P and (1)H) and mass spectrometry. Their shapes and sizes were established using Merck Molecular Force Field (MMFF) simulations. In addition, their approximate sizes were further supported by pulsed-field-gradient spin-echo (PGSE) NMR experiments.

摘要

通过多组分、配位驱动、无模板自组装，我们描述了一种构建功能化金属超分子四方棱柱的新方法。将四(4-吡啶基苯基)乙烯、90°Pt(II)受体与双吡啶或羧酸配体结合，这些配体带有羟基或氨基、疏水性烷基链或电化学活性的二茂铁，在温和条件下得到了一套七种自组装的四方棱柱。这些三维金属超分子通过多核 NMR((31)P 和 (1)H)和质谱进行了表征。它们的形状和大小使用默克分子力学场(MMFF)模拟进行了确定。此外，通过脉冲梯度自旋回波(PGSE)NMR 实验进一步支持了它们的近似大小。
