| 摘要: 水热条件下采用Pb(NO3)2和4-氯苯乙酸作为反应物合成出1个新的一维铅配位聚合物[Pb(4-cpa)2(H2O)]n(1)(4-Hcpa=4-氯苯乙酸)，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：μ3桥联的4-氯苯甲酸将铅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11发射蓝色荧光，且在422nm处的荧光寿命为5.3ns。以除草剂-精喹禾灵为对照品，考察了配体4-Hcpa和配合物1的生物活性。 |

| Abstract: Anew 1D lead(Ⅱ) coordination polymer, [Pb(4-cpa)2(H2O)]n (1, 4-cpa=4-chlorophenylacetate), has been hydrothermally synthesized and structurally characterized by elemental analysis, IR spectroscopy, TGA, powder X-ray diffraction and single crystal X-ray diffraction. Structural determination reveals that 1 exhibits an interesting 1D chain structure constructed by 4-cpa ligands. Solid-state 1 emits the intensely blue photoluminescence with fluorescence lifetime of 5.3 ns (422 nm) at room temperature. The 4-Hcpa ligand and complex 1 have been screened for their phytogrowth-inhibitory activities against Brassica napus L. and Echinochloa crusgalli L., and the results are compared with the activity of quizalofop-p-ethyl. |
