在溶剂热条件下合成了2个锌(Ⅱ)/镉(Ⅱ)配位聚合物:{[Zn(1,3-bip)(bpdc)]·0.5H2bpdc}n(1),{[Cd2(1,3-bip)2(bpdc)2]·DMF}n(2),H2bpdc=4,4′-联苯二甲酸,1,3-Bip=1,3-二(咪唑基)丙烷。并通过X射线单晶衍射,粉末XRD、红外光谱、元素分析以及热重分析对其结构进行表征。单晶解析结果表明:配位聚合物1是一个五重穿插3D→3D三维空间网络结构,配位聚合物2是一个二重穿插的2D→2D二维的(4,4)网格层状结构。另外,研究了2个配位聚合物在室温下的热稳定和荧光性能。
Two zinc (Ⅱ) / cadmium (Ⅱ) coordination polymers were synthesized under solvothermal conditions: {[Zn (1,3-bip) (bpdc)] · 0.5H2bpdc} n 1,3-bip) 2 (bpdc) 2] · DMF} n (2), H2bpdc = 4,4’-biphenyldicarboxylic acid and 1,3-Bip = 1,3-bis (imidazolyl) propane. Its structure was characterized by X-ray single crystal diffraction, powder XRD, FTIR, elemental analysis and TG analysis. The results of single crystal analysis show that the coordination polymer 1 is a five-dimensional intercalated 3D → 3D three-dimensional network structure, and the coordination polymer 2 is a double-intercalated 2D → 2D two-dimensional (4,4) structure. In addition, the thermal stability and fluorescence properties of two coordination polymers at room temperature were studied.
