摘要: 在水热条件下, 分别用过渡金属离子Zn(Ⅱ)和Co(Ⅱ)与混合手性羧酸和含氮配体反应, 合成了2个手性金属-有机配位聚合物[M(D-cam)(H2mbdpz)]n[M=Zn(1), Co(2); D-H2cam=D-(+)-樟脑酸; H2mbdpz=4,4'-亚甲基二(3,5-二甲基吡唑)]. 通过单晶X射线衍射、粉末X射线衍射、元素分析、热重分析及荧光分析对其结构、组成和性质进行了表征. 单晶结构分析表明, 配合物1和2是异质同晶的手性三维开放骨架结构, 具有单节点三连接的ThSi2型网络拓扑结构.

关键词: 金属-有机配位聚合物, D-(+)-樟脑酸, 手性, 荧光性质

Abstract: Two new homochiral metal-organic coordination polymers[M(D-cam)(H2mbdpz)]n[M=Zn(complex 1), Co(complex 2); D-H2cam=D-(+)-camphoric acid, H2mbdpz=4,4'-methylenebis(3,5-dime-thylpyrazole)] were prepared by mixing ligands with corresponding transition metal ions under hydrothermal conditions. The complexes were characterized by means of single-crystal X-ray diffraction, elemental analysis, thermograrimetri analysis(TGA), powder X-ray diffraction(XRD) and photoluminescent(PL) spectrometry. X-ray crystallography reveals that complexes 1 and 2 are isomorphous and homochiral, exhibiting the three-dimensional open structure with a ThSi2 type of uninodal 3-connected networks.

Key words: Metal-organic coordination polymer, D-(+)-Camphoric acid, Chirality, Fluorescence property
