一个二维镉配位聚合物的合成、结构及荧光性能研究

摘要

在水热条件下，一个新的二维镉配位聚合物｛[Cd（1，3-PDA）（ppene）]·H2O｝n （1）通过Cd（NO3）2·4H2O，1，3-phenylendiacetic acid以及4-pyr-poly-2-ene的反应而被合成.该化合物通过红外光谱，元素分析以及X-射线单晶衍射进行了表征. X-射线单晶结构分析表明，该化合物属于三斜晶系，Pī空间群，晶胞参数：a=9.5248（19），b=10.430（2），c=1.1389（2） nm，α=88.65（3）°，β=86.79（3）°，γ=69.70（3）°，V=1.0595（3） nm3，Z=2， R1=0.0304，wR2=0.0748. CCDC号为1038885.化合物1为一个二维（4，4）网格结构的网络.我们对该化合物的荧光性质也作了研究.%A novel two dimensional cadmium coordination polymer,formulated as{[Cd(1,3-PDA)(ppene)]·H2O}n (1) has been synthesized through hydrothermal reaction between Cd(NO3)2·4H2O and 1,3-phenylendiacetic acid (1,3-H2PDA)in the presence of 4-pyr-poly-2-ene(ppene). The complex was structurally characterized by infra⁃red spectroscopy,elemental analysis and single crystal X-ray diffraction.Single-crystal X-ray diffraction analysis shows that the compound belongs to the triclinic system with space group Pī and a=9.524 8(19),b=10.430(2),c=1.138 9(2) nm,α=88.65(3)° ,β=86.79(3)° ,γ=69.70(3)° ,V=1.059 5(3) nm3,Z=2,R1 =0.030 4,wR2=0.074 8. CCDC number 1038885. Compound 1 exhibits a two dimensional(4,4)network.Photoluminescence properties of 1 was also investigated.
