We present a general strategy for the synthesis of stable 3-D metallosupramolecular tetragonal prisms in which multicomponent coordination-driven self-assembly allows for single supramolecular species to be formed. The appropriate stoichiometric combination of a tetraphenylethylene-based tetratopic donor (1), a linear dipyridine donor (2), and a 90 degrees platinum metal complex (3) affords tetragonal prisms (4) as single products. The compounds have been characterized by multinuclear NMR spectroscopy and electrospray ionization mass spectrometry. The size of the supramolecules was determined by pulsed-gradient spin-echo NMR and modeled with molecular force field simulation methods.
我们提出了一种通用策略,用于合成稳定的三维金属超分子四方棱柱,其中多组分配位驱动的自组装允许形成单一的超分子物种。基于四苯乙烯的四齿供体(1)、线性联吡啶供体(2)和 90 度铂金属配合物(3)的适当化学计量组合提供了作为单一产物的四方棱柱(4)。这些化合物已通过多核 NMR 光谱和电喷雾电离质谱进行了表征。超分子的大小通过脉冲梯度自旋回波 NMR 确定,并通过分子力场模拟方法进行建模。
