摘要

本研究制备并描述了两种新的顺磁性超分子螺旋体，其化学式为 (X@[Ni2L3])3+（X = Cl 或 Br；L = 双吡唑吡啶配体）。这种金属的螺旋状化合物非常罕见，几乎没有作为阴离子物种宿主的实例。质谱法和顺磁核磁共振法明确证明了这种新组装体在溶液中的持久性。这使得配位[Ni2]宿主对 Cl- 而非 Br- 的偏好得以确定，这与 DFT 计算结果一致。这些结果表明，使用金属杂环化合物作为合适的体系来选择性地封装溶液中的特定阴离子是大有可为的。

Guest selectivity of [Ni2] supramolecular helicates

Two new paramagnetic supramolecular helicates with formula (X@[Ni2L3])3+ (X = Cl, or Br; L = a bis-pyrazolylpyridine ligand) have been prepared and are described. Helicates of this metal are very rare with virtually no prior examples of them acting as host of anionic species. The persistence in solution of the new assemblies has been demonstrated unambiguously by mass spectrometry and paramagnetic NMR. This has allowed to establish the preference of the coordination [Ni2] host for Cl− over Br−, in agreement DFT calculations. These results show the promise of the use of metallohelicates as suitable systems for the selective encapsulation of specific anions in solution.
