水热条件下采用Cd(NO3)2·4(H2O),4′-羟基联苯-4-甲酸和1,3-二吡啶基丙烷作为反应物合成出一个新的一维镉配位聚合物{[Cd(4′,4-Hhbc)2(bpp)2]}n(1)(4′,4-H2hbc=4′-羟基联苯-4-甲酸,bpp=1,3-二吡啶基丙烷),并分别用元素分析、红外光谱、差热分析、X-射线粉末衍射、紫外吸收光谱和X-射线单晶衍射等表征了该结构。晶体结构分析结果表明:μ2桥联的1,3-二吡啶基丙烷将镉金属离子连接成一维链结构。荧光分析表明常温固态下配合物1发射蓝色荧光,且在440 nm处的荧光寿命为3.2 ns。
Under the hydrothermal conditions, Cd (NO3) 2.4 · H2O (H2O), 4’-hydroxybiphenyl-4-carboxylic acid and 1,3-dipyridylpropane were used as reactants to synthesize a new one-dimensional cadmium coordination polymer {[Cd (4 ’, 4-Hhbc) 2 (bpp) 2]} n (1) (4’, 4-H2hbc = 4’-hydroxybiphenyl-4-carboxylic acid, bpp = Propane), and the structure was characterized by elemental analysis, infrared spectroscopy, differential thermal analysis, X-ray powder diffraction, UV absorption spectra and X-ray single crystal diffraction. Crystal structure analysis results show that: μ2 bridged 1,3-dipyridyl propane cadmium metal ions connected into a one-dimensional chain structure. Fluorescence analysis showed that complex 1 emits blue fluorescence at room temperature and has a fluorescence lifetime of 3.2 ns at 440 nm.
