The design and synthesis of coordinative truncated tetrahedra is described. The 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 tetrahedron can act as a host toward 1,3,5-triphenylbenzene. The truncated tetrahedral structures and the host-guest complex were identified using multinuclear ((31)P and (1)H) NMR spectroscopy, electrospray ionization mass spectrometry, X-ray crystallography, and pulsed-field-gradient spin-echo NMR, along with computational simulations.
描述了配位截断四面体的设计和合成。在温和条件下,使用 90°有机铂受体和具有六重对称的六吡啶配体,实现了截断四面体的配位驱动自组装。该四面体可以作为 1,3,5-三苯基苯的主体。使用多核((31)P 和(1)H)NMR 光谱、电喷雾电离质谱、X 射线晶体学和脉冲场梯度自旋回波 NMR 以及计算模拟,确定了截断四面体结构和主体-客体配合物。
