| 中文摘要: |
| 采用水热法,用4,4′-(2,5-二(甲硫基)-1,4-亚苯基)二吡啶(L)和4,4′-二苯醚二甲酸(H2OBA)与Zn(NO3)2·6H2O,生成了一个三维配合物{}n(1)。X-单晶射线分析表明,配合物是为单斜晶系,C2/c空间群,分子量Mr=650.09,a=2.526 5(2) nm,b=1.462 3 (1) nm,c=1.715 9(1) nm,β=97.37(2)°,V=6.286 9(3) nm3,Z=4,Dc=1.458 g/cm3,F(000)=2 832,S=1.157,R1=0.078 5,wR2=0.194 6 (I>2σ(I))。配合物1中,Zn与配体L和质子化的4,4′-二苯醚二甲酸分别形成了一维链,而两条一维链相互来链接形成三维结构。另外对配合物热稳定性和荧光进行了测试。有趣的是,水中少量的Fe3+可以猝灭配合物1的荧光,证明配合物1对检测废水中的Fe3+具有潜在的应用价值。 |

| A new coordination compound {}n (1) was prepared by hydrothermal method using (L=4,4′-(2,5-bis(methylthio)-1,4-phenylene, H2OBA=4,4′-oxybisbenzoic acid) and Single-crystal X-raydiffraction analysis revealed that the compound crystallines in monoclinic crystal system, space group C2/c with Mr=650.09, a=2.526 5(2) nm, b=1.462 3(1) nm, c=1.715 9(1) nm, β=97.37(2)°, V=6.286 9(3) nm3,Z=4,Dc=1.458 g/cm3,F(000)=2 832,S=1.157, R1=0.078 5, wR2=0.194 6 (I >2σ(I)). In compound 1, Zn coordinated with L and protonated OBA2－to form two 1D chains, and the chains are linked to form a 3D network. Thermal stability and luminescence property were studied. Interestingly, the luminescent emission of 1 can be quenched by the addition of trace of amount of Fe3+, demonstrating its potential application for sensitively detecting Fe3+. |
