通过水热方法合成2个基于5-(3-氨基苯基)四唑(apt-)配体的金属配合物[Pb2(phen)2(H2O)2(apt)4](Ⅰ)和[Zn2(phen)2(apt)2(N3)2]·H2O(Ⅱ),并进行结构表征和荧光性能的测定.结构研究表明:2个配合物均呈现双核的分子结构,其中配合物Ⅰ中1对apt-离子连接2个独立的PbII八面体,配合物Ⅱ则由2个对称的叠氮离子连接2个中心对称的ZnII离子,2个双核分子进一步通过氢键作用拓展形成二维超分子层.此外,2个配合物均具有良好的热稳定性且表现出由金属到配体电荷转移的荧光发射峰,表明其在荧光材料中具有潜在的应用前景.
Two metal complexes based on 5- (3-aminophenyl) tetrazolium (apt-) ligand [Pb2 (phen) 2 (H2O) 2 (apt) 4] (I) and [Zn2 (phen) 2 (apt) 2 (N3) 2] · H2O (Ⅱ). The structure and fluorescence properties of the complexes were studied. The structural studies showed that the two complexes showed the binuclear molecular structure. Two independent PbII octahedrons are connected to apt- ions, and two symmetric ZnII ions are connected by two symmetric azide ions in complex II. Two of the two dinuclear molecules further expand to form two-dimensional supramolecular layers by hydrogen bonding In addition, both complexes have good thermal stability and show the fluorescence emission peak from metal to ligand charge transfer, indicating that it has potential applications in fluorescent materials.
