The synthesis and properties of a 2-to-2' 18-to-18' doubly linked Ni(ii) norcorrole dimer are described. It adopts a highly planar structure, resulting in effective electronic interactions between the constituent norcorrole units. Nevertheless, each norcorrole unit exhibits substantial antiaromaticity, which stands in sharp contrast to stacked norcorrole dimers.
描述了一种2至2'、18至18'双连接的Ni(ii) 降卟啉二聚体的合成及性质。它采用高度平面的结构,导致组成的降卟啉单元之间产生有效的电子相互作用。然而,每个降卟啉单元都表现出显著的反芳香性,这与堆叠的降卟啉二聚体形成鲜明对比。
