摘要: 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)。 |

Abstract: A new 1D zinc(Ⅱ) coordination polymer {[Zn(Hhbc)2(bpp)]H2O}n (1) (Hhbc=4'-Hydroxyl-biphenyl-4-carboxylate, bpp=1,3-bis(4-pyridyl)propane) has been synthesized by hydrothermal method and characterized by elemental analysis, IR, TGA, powder X-ray diffraction and single-crystal X-ray diffraction. The carboxylate oxygens of two different Hhbc ligands connect one ZnⅡ ion in bidentate-chelating and monodentate coordinated modes to form mononuclear zinc building blocks, which are further linked into a 1D infinite chain through trans-bpp ligands. These chains are further linked into a 2D supramolecular network through water-hydroxyl tetramers involving the free water molecules and hydroxyl groups of Hhbc ligands. Furthermore, the luminescent property of complex 1 was investigated at room temperature. CCDC: 919045. |
