We present a general strategy for the synthesis of stable, multifunctional cuboctahedral complexes in which coordination-driven self-assembly allows for precise control over positioning of either ferrocene or crown ether functionalities. The appropriate stoichiometric combination of functionalized 120 degree diplatinum acceptor units with tritopic donor units afforded supramolecular cuboctahedra with covalently linked functional groups. The compounds are characterized by multinuclear NMR spectroscopy, electrospray ionization mass spectrometry, and electrochemistry.
我们提出了一种合成稳定的多功能立方八面体配合物的通用策略,其中配位驱动的自组装能够精确控制二茂铁或冠醚官能团的定位。功能化的120度双铂受体单元与三齿供体单元的适当化学计量组合产生了具有共价连接官能团的超分子立方八面体。通过多核核磁共振光谱、电喷雾电离质谱和电化学对这些化合物进行了表征。
