含有1,4,7-三苄基-1,4,7-三氮杂环壬烷的两个双核铜配合物的合成、表征及其与DNA的相互作用

摘要

合成了2个含有1,4,7-三苄基-1,4,7-三氮杂环壬烷(Bn3tacn)的双核铜配合物:[Cu2(Bn3tacn)2(m-bdc)(CH3CN)3(H2O)dClO4(1)和[Cu2(Bn3tacn)2(OH)2](ClO4)2 (2).配合物1由间苯二甲酸采取单双齿方式桥连Cu(Ⅱ)离子,配合物2由OH桥连.配合物1和2晶体均属于单斜晶系,分别为P21/c空间群和C2/c空间群.分别对2个配合物进行了红外光谱、紫外-可见光谱和元素分析表征.研究了配合物1与DNA的相互作用,对配合物2进行了循环伏安测试.%Two binuclear copper(l) complexes were prepared with ligand 1,4,7-tribenzyl-1,4,7-triazacyclononane(Bn3tacn):[Cu2(Bn3tacn)2(m-bdc)(CH3CN)3(H2O)2]ClO4 (1) and [Cu2(Bn3tacn)2(OH)2](ClO4)2 (2).The copper(Ⅱ) ion in complex 1 is bridged by the m-benedicarboxylic acid (m-bdc) adopting bis(bidentate/monodentate) coordination type and is bridged by theμ-OH in complex 2.Complexes 1 and 2 crystalize in the monoclinic system,space group P21/c and C2/c,respectively.IR,UV-Vis,element analysis,binding with DNA properties of the complex 1 and cyclic voltammogram of complex 2 have been studied.
