摘要
以5-(2-羟乙氧基)-1,3-苯二甲酸二甲酯(Me2L)为配位前驱物分别与二水合醋酸镉和三水合醋酸铅在水热条件下发生原位水解-配位反应,得到2个基于5-(2-羟乙氧基)-1,3-苯二甲酸配体和Cd(Ⅱ)或Pb(Ⅱ)的三维金属有机框架化合物{[Cd(L)(H2O)2]·1.5H2O}n (1)和[Pb(L)·H2O]n (2)。对这2个化合物进行了红外、元素分析和X射线单晶衍射分析,获得了其单晶结构并进一步使用X射线粉末衍射技术证明了所获得的产物具有单一晶相。对比固态下配体和2个金属有机框架化合物的荧光发射性质,能发现金属有机框架化合物较配体有了较大的红移,且红移程度与金属离子种类有关,Pb(Ⅱ)离子构建的金属有机框架化合物具有更大的红移程度。
Cadmium(Ⅱ) and lead(Ⅱ) based three-dimensional metal-organic frameworks(MOFs), namely {[Cd(L)(H2O)2]·1.5 H2O}n(1) and [Pb(L)·H2O]n(2), have been obtained through hydrothermal synthesis method using dimethyl 5-(2-hydroxyethoxy) isophthalic acid(Me2L) as a precursor and metal acetate.The crystal structures of two MOFs wererevealed by single-crystal X-ray diffraction analysis and further confirmed by infrared spectrum(IR) and elementanalysis(EA).The XRD analysis of the MOFs ensured the single-crystal phase of the MOFs.The fluorescence emis-sion property of two MOFs and H2L in the solid-state was investigated.Compared to the emission spectrum of Me2L,the emission maximum of compounds1 and all had red - shift but 2 shifted more severe.CCDC: 1986790,1;1986793,2.
