【摘要】：近年来,由于金属有机框架(MOFs)的独特结构和其在气体存储、传感器、分离、催化、离子交换、磁性、发光等方面的潜在应用,引起了人们相当大的关注。在功能配合物的领域,由于吡啶多羧酸配体拥有多样化的配位模式、较强的配位能力和其构筑的配合物表现出的优良性能,使得吡啶多羧酸配体构筑的配合物成为热门研究课题之一。在本篇论文中,主要研究了由吡啶多羧酸配体构筑的配合物的结构和性能。我们选用了两种这类配体,分别为:4-(2,4,6-三羧酸苯基)-2,2',6',2''-三联吡啶(O-tcpt),4-(2,4,6-三羧酸苯基)-4,2',6',4'-三联吡啶(P-tcpt),利用水热合成的方法成功地得到了17个配合物:{[Pb2(O-tcpt)]·CH3OH·3H2O}n(1),[Pb2(O-tcpt)(μ2-Cl)H2O]n(2),{[Pb2(O-tcpt)2]·8H2O}n(3),{[Cu(O-tcpt)]·3/2CH3OH·3/2H2O}n(4),{[Cu(O-tcpt)]·2H2O}n(5),{[Cu(O-tcpt)Cl]·1/2CH3CH2OH}n(6),{[Cu(O-tcpt)H2O]·1/2SO4·2H2O}n(7),{[Ni2(O-tcpt)22H2O]·3/2CH3CH2OH·7/4H2O}n(8),[Ni(O-tcpt)2]·5H2O(9),[Mn(O-tcpt)2]·4H2O]n(10),{[Mn(O-tcpt)]·CH3CH2OH}n(11),{[Mn(O-tcpt)]·2H2O}n(12),{[Cd(O-tcpt)]·2H2O}n(13),{[Mn(P-tcpt)]·3H2O}n(14),{[Mn2(P-tcpt)·2H2O]·1/4CH3OH·3H2O}n(15),{[Mn(P-tcpt)]·H2O}n(16),{[Co2(P-tcpt)2]·CH3CH2OH·2H2O}n(17)。利用单晶X射线衍射仪解析了这17个配合物的结构,发现这两种配体都有较强的配位能力,表现出多种的配位模式,增加了配合物结构的多样性。并且对配合物进行了元素分析、红外光谱表征以及粉末衍射分析。此外,我们还对部分配合物的荧光和磁性进行了分析和表征。并且研究了配合物对大肠杆菌,金黄色葡萄球菌,肠炎沙门氏菌和枯草芽孢杆菌的抗菌活性,发现了这些配合物对枯草芽孢杆菌表现出了抗菌单一性。在此过程中还探讨了部分配合物结构和性能的联系。
[Abstract]:In recent years, due to the unique structure of MOFs and their potential applications in gas storage, sensors, separation, catalysis, ion exchange, magnetism, luminescence, etc. In the field of functional complexes, because of the variety of coordination modes, strong coordination ability and excellent performance of the complexes constructed by pyridine polycarboxylic acid ligands. The complexes constructed by pyridine polycarboxylic acid ligands have become one of the hot research topics. The structure and properties of the complexes constructed from pyridine polycarboxylic acid ligands were studied. (2) tripyridine-O-tcpttrichloropyridine (OTCPT) 4-trichlorobarboxylic acid (TCA) -4-trichlorobarboxylic acid (TCA) -4-tripyridine (P-tcpt). A total of 17 complexes have been successfully synthesized by hydrothermal synthesis: {. [CH3OH 路3H2O]. [PB _ 2o _ t _ cptt _ (渭 _ 2-Cl _ (H _ 2O)] n ~ (2 +), {. [Pb2(O-tcpt)2] 路8H _ 2O}.

The structures of these 17 complexes were elucidated by single crystal X-ray diffractometer. It was found that the two ligands had strong coordination ability, showed various coordination modes, increased the diversity of the complex structure, and analyzed the complexes by elemental analysis. In addition, the fluorescence and magnetic properties of some complexes were also analyzed and characterized, and the complexes for Escherichia coli and Staphylococcus aureus were also studied. The antimicrobial activity of Salmonella enteritidis and Bacillus subtilis showed that these complexes showed a single antibacterial activity against Bacillus subtilis. The relationship between the structure and properties of some complexes was also discussed.
