A series of diamagnetic macrocyclic nickelcomplexes I bearing substituted dibenzotetraaza[14] annulene ligands with methyl and/or phenyl groups on NCR moieties and methyl or nitro groups on the phenylen units have been prepared by Ni templatesynthesis from the corresponding 1,3-diketo- and 1,2-diamino-benzene components. 1H and 13C NMR data are reported and interpreted in terms of sterical and electronical
一系列抗磁性大环镍配合物 I 带有取代的二苯并四氮杂 [14] 轮烯配体,在 NCR 部分带有甲基和/或苯基,在亚苯基单元上带有甲基或硝基,通过 Ni 模板合成从相应的 1,3-二酮- 和 1,2-二氨基苯组分。1H 和 13C NMR 数据被报告并解释为这些取代基在配体上引起的空间和电子变化,并与理论计算结果进行比较。进一步的表征基于 IR、UV/Vis 和质谱测量。
