【摘要】：本文制备了一个新型的二羧基功能化的希夫碱配体1,2-环己二胺-N,N'-二(~(3-)甲氧基-5-对羧基苯偶氮基-邻羟亚苄基)(H_4L),基于该配体和中性配体:内消旋-5,7,7,12,14,1~(4-)六甲基-1,4,8,11-四氮杂环十四烷(teta),通过水热法合成了四个配位聚合物:[Fe_2(L)(OH)(DMF)]·[OH](1),[(CH_3)_2NH_2]_2·[Mn_3(L)_2(H_2O)_4]·2DMF(2),[Ni_2L(teta)]·2DMF·H_2O(3)和[(CH_3)_2NH_2]·[CuHL]·H_2O(4)。在配合物1中,L~(4-)阴离子将Fe~(3+)离子连接成独特的双核双链结构,相邻的链通过氢键作用形成二维超分子层。在2中,L~(4-)阴离子将Mn~(2+)离子连接为二维层。在3中,Ni~(2+)离子被L~(4-)阴离子和teta配体连接为一维链。配合物4中,HL~(3-)阴离子将Cu~(2+)离子连接为二聚体,相邻的二聚体通过氢键作用形成了二维超分子层。本论文用元素分析、红外光谱、X-射线粉末衍射和紫外可见光谱对配合物进行了表征。此外,还考察了化合物2对染料的吸附性质。结果表明,2可以有效吸附亚甲基蓝、金橙II和中性红三种染料。
[Abstract]:In complex 1, the Fe~(3 ion is connected by the anions to form a unique binuclear double-stranded structure, and the adjacent chains form a two-dimensional supramolecular layer by hydrogen bonding.The Mn~(2 ion was connected into a two-dimensional layer by the anions in 2.The teta ligands are linked to the anions of the 3 ~ (+) ~ (3) ~ (-) ~ (- () ~ (2) ~ (-) ~ (2)).In complex 4, the Cu~(2 ion is connected to the Cu~(2 ion by the anions. The adjacent dimers form a two-dimensional supramolecular layer by hydrogen bonding.The complexes were characterized by elemental analysis, X-ray powder diffraction and UV-vis spectra.In addition, the adsorption properties of compound 2 to dyes were also investigated.The results showed that the methylene blue, gold orange II and neutral red dyes could be effectively adsorbed.
