水热条件下采用Zn(NO3)2.6H2O,4′-羟基-联苯-4-羧酸和1,3-二(4-吡啶基)丙烷作为反应物合成出一个新的一维锌金属配位聚合物{[Zn(Hhbc)2(bpp)].H2O}n(1)(Hhbc=4′-羟基-联苯-4-羧酸,bpp=1,3-二(4-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:化合物1为一维链状锌(Ⅱ)配位聚合物,通过分子间的O-H…O氢键作用,一维链进一步被连接成二维超分子结构。荧光分析表明常温固态下配合物1发射蓝色荧光,荧光寿命为3.08 ns(480 nm)。
A new one-dimensional zinc metal complex was synthesized by hydrothermal reaction of Zn (NO3) 2.6H2O, 4’-hydroxy-biphenyl-4-carboxylic acid and 1,3-bis (4-pyridyl) Homopolymer {[Zn (Hhbc) 2 (bpp)]. H2O} n (1) (Hhbc = 4’-hydroxy-biphenyl- Propane), and the structure was characterized by elemental analysis, infrared spectroscopy, differential thermal analysis, X-ray powder diffraction and single crystal X-ray diffraction. The results of crystal structure analysis show that compound 1 is a one-dimensional chain-like zinc (Ⅱ) coordination polymer, and the one-dimensional chain is further connected into a two-dimensional supramolecular structure through the O-H ... O hydrogen bonding between molecules. Fluorescence analysis showed that the complex 1 emits blue fluorescence at room temperature and the fluorescence lifetime is 3.08 ns (480 nm).
