【摘要】：以多齿含氮杂环和羧酸为混合配体,与过渡金属盐构筑的配位聚合物因其丰富多样的拓扑结构和在诸多前沿领域诱人的应用价值而备受关注。通过金属中心的合理选择,有机组件的精妙设计和反应条件的精密调控,定向组装出性能优异的配位聚合物已经成为配位化学的重点研究课题之一。采用水热合成法,以三种新型的柔性噻苯咪唑配体:1,3-二(2-(4-噻唑基)苯并咪唑-1-基)丙烷(btbp),1,4-二(2-(4-噻唑基)苯并咪唑-1-基)丁烷(btbb)和1,6-二(2-(4-噻唑基)苯并咪唑-1-基)已烷(btbh)为主配体,多种二元羧酸为辅助配体,与三种金属盐合成了12个新型配合物。通过X-射线单晶衍射、X-射线粉末衍射、元素分析以及红外光谱对配合物进行了一系列表征,并对它们的拓扑结构进行分析。以Co(Ⅱ)离子为配位中心,btbb和不同二元羧酸进行混配,构筑4个新型钴配合物。配合物1~3均为二维3-连接的hcb层状结构,配合物1和3通过氢键作用分别拓展为三重互穿的三维mog网络和(3,4)-连接的xww-3,4-P21/c超分子拓扑网。配合物2也通过π-π堆积作用延展成三维超分子结构。配合物4为双核结构,通过氢键作用形成3,4L39超分子拓扑网。以btbp,btbb和btbh和多种二元羧酸为混合配体与d10金属离子(Cd(Ⅱ)/Zn(Ⅱ))配位,构筑了8个未见报道的配合物。配合物5为三维三重互穿的mog骨架。配合物7是(3,4)-连接的三维3,4T10拓扑网。配合物6,8和11都是二维(6,3)的hcb拓扑结构,配合物11进一步拓展为cem-d氢键拓扑网。配合物9,10和12为不同形式的一维链,通过π-π堆积延展成二维结构。配合物5,7,8和9都表现出较高的热稳定性;除配合物3和4外,其他配合物均具有良好的荧光特性。此外,配合物1,3,6,7和11对甲基橙染料均表现出较高的催化降解活性,可作为潜在的催化新材料。
[Abstract]:With polydentate heterocyclic nitrogen and carboxylic acid as mixed ligands, coordination polymers constructed with transition metal salts have attracted much attention due to their rich and diverse topological structures and attractive application value in many frontier fields. Through the rational selection of metal centers, the delicate design of organic components and the precise control of reaction conditions, the directional assembly of coordination polymers with excellent performance has become one of the key research topics in coordination chemistry. Three novel flexible thiamidazole ligands, 1- (4- (4-thiazolyl) benzimidazole-1-yl) propane (btbp), were synthesized by hydrothermal method with three novel ligands: 1- (4- (4-thiazolyl) benzimidazole-1-yl) propane. The main ligands of 1- (4- (4-thiazolyl) benzimidazole-1-yl) butane (btbb) and 1- (4- (4-thiazolyl) benzimidazole-1-yl) hexane (btbh), with a variety of dicarboxylic acids as auxiliary ligands, Twelve new complexes were synthesized with three metal salts. The complexes were characterized by X-ray single crystal diffraction, X-ray powder diffraction, elemental analysis and infrared spectroscopy, and their topological structures were analyzed. Four new cobalt complexes were constructed by using Co (鈪，
