diffraction experiments in conjunction with long range corrected density functional theory. The heterocyclic amines on the naphthoquinone ring render diverse crystal structures. It has been shown that bromine substitution influences the planarity and mutual orientation of naphthoquinone and heterocycles in aminonaphthoquinone ligands. The 2MPA, 3MPA, 2EPA, 2AET aminonaphthoquinone ligands crystallize in the monoclinic
溴取代的氨基萘醌配体。2-(2'-氨基甲基吡啶基)-3-溴-萘-1,4-二酮; (2MPA),2-(3'-氨基甲基吡啶基)-3-溴-萘-1,4-二酮; (3MPA),2-(2'-氨基乙基吡啶基)-3-溴-萘-1,4-二酮; (2EPA)和2-(2'-氨基甲基硫代苯基)-3-溴萘-1,4-二酮(2AMT)和2-(2'-氨基乙基硫代苯基)-3-溴萘-1,4-二酮(2AET )已结合单程X射线衍射实验和远距离校正密度泛函理论进行了表征。萘醌环上的杂环胺具有多种晶体结构。已经表明,溴取代影响氨基萘醌配体中萘醌和杂环的平面度和相互取向。2MPA,3MPA,2EPA,P。此外,2MPA和2EPA的分子堆积揭示了二聚体结构,而3MPA和2AMT则具有“阶梯式”分子排列。从c轴向下看,图2AET显示了“蝶形”排列。在这些配体的紫外可见光谱中观察到较宽的电荷转移带(400–600 nm)。此外,2MPA和2EPA对Cu
