描述了配位截角四面体的设计与合成。在温和的条件下,利用90°有机铂受体和六重对称的六吡啶配体实现了配位驱动的截顶四面体自组装.该组装体可以作为1,3,5-三苯基苯的主体。截断四面体结构和主体-客体复合物使用多核(31 P和1H)NMR光谱、电喷雾电离(ESI)质谱、X射线晶体学和脉冲场梯度自旋回波(PGSE)NMR,沿着计算模拟来鉴定。
The design and synthesis of coordinative truncated tetrahedra is described. Coordination-driven self-assembly of a truncated tetrahedron was achieved using 90° organoplatinum acceptors and a hexapyridyl ligand with six-fold symmetry under mild conditions. This assembly can act as a host towards 1,3,5-triphenylbenzene. The truncated tetrahedral structures and the host-guest complex were identified using multinuclear (31P and 1H) NMR spectroscopy, electrospray ionization (ESI) mass spectrometry, X-ray crystallography, and pulsed field gradient spin-echo (PGSE) NMR, along with computational simulations.
