摘　　要：采用水热法,利用五羧酸配体3,5-二(2',4'-二羧基苯基)苯甲酸(H_(5)L)制备了2种结构相似的镧系-钴异核双金属有机骨架(Ln-Co-MOF):(C_(2)H_(6)NH_(2))_(5){[Eu_(9)Co(L)_(6)(H_(2)O)_(5)(OH)_(4)]·5DMF}_(n)(1)、(C_(2)H_(6)NH_(2))_(2){[Sm_(9)Co(L)_(6)(H_(2)O)_(3)Cl]·5DMF}_(n)(2),并通过单晶X射线衍射、粉末X射线衍射、热重、红外、荧光光谱和磁性对其进行了结构表征和性能测试。结果表明,配合物1和2均属于三方晶系R3空间群,均具有新颖的三维结构和良好的热稳定性。其中配合物1具有较强的荧光性能,可以灵敏地识别药物分子柳氮磺吡啶和有机分子戊二醛,检出限分别可以达到0.95和2.10μmol·L^(-1)。此外,配合物1和2在1 kOe时均具有反铁磁性。We used pentacarboxylic acid ligand 3,5‑di(2′,4′‑dicarboxylphenyl)benzoic acid(H_(5)L)to synthesize two structural similarity lanthanide‑cobalt heteronuclear bimetallic organic frameworks(Ln‑Co‑MOFs)by hydrothermal method:(C_(2)H_(6)NH_(2))_(5){[Eu_(9)Co(L)_(6)(H_(2)O)_(5)(OH)_(4)]·5DMF}_(n)(1),(C_(2)H_(6)NH_(2))_(2){[Sm_(9)Co(L)_(6)(H_(2)O)_(3)Cl]·5DMF}_(n)(2).The structures were characterized and the property was tested by single crystal X‑ray diffraction,powder X‑ray diffraction,thermogravimetry,infrared,fluorescence spectra,and magnetism.The results show that 1 and 2 both belong to the trigonal R3 space group and have novel 3D structures and good thermal stability.Among them,1 has strong fluorescence properties,which can sensitively identify drug molecules sulfasalazine and organic molecules glutaraldehyde.The detection limits could reach 0.95 and 2.10μmol·L^(-1),respectively.In addition,1 and 2 were antiferromagnetic at 1 kOe.CCDC:2343234,1;2343236,2.
