以5-氨基四氮唑(HATz),异烟酸(HPyc)和ZnSO4·7H2O或Zn(NO3)2·6H2O为反应物,在DMF溶剂热条件下分别得到了2个锌(Ⅱ)配位聚合物{[(CH3)2NH2]·[Zn(ATz)(SO4)]}n(1)和{[Zn(ATz)(Pyc)]·0.5DMF}n(2),并对它们的组成和结构进行了表征。配合物1是由4-连接(4,4)网络拓扑的[Zn(ATz)(SO4)]nn-二维阴离子层和[(CH3)2NH2]+阳离子间通过氢键作用形成的二维波浪层结构。配合物2则是1个二重穿插的4-连接金刚烷拓扑的三维微孔金属-有机框架结构,客体DMF分子填充在孔道内。室温下的固体荧光实验表明,在350 nm的光激发下,配合物1和2分别在为445 nm和458 nm处出现强烈的荧光发射。
Two zinc (Ⅱ) coordination sites were obtained under the solvothermal conditions of DMF with 5-aminotetrazole (HATz), isonicotinic acid (HPyc) and ZnSO4 · 7H2O or Zn (NO3) The polymers {[(CH3) 2NH2] · [Zn (ATz) (SO4)]} n (1) and {[Zn (ATz) (Pyc)] · 0.5DMF} n (2) The structure was characterized. Complex 1 is a two-dimensional wave formed by hydrogen bonding between [Zn (ATz) (SO4)] nn-two-dimensional anion layers and [(CH3) 2NH2] + cations in a 4-junction (4,4) network topology Layer structure. Complex 2 is a three-dimensional microporous metal-organic framework with a double interspersed 4-linked adamantane topography. The guest DMF molecules are filled in the pores. Solid-state fluorescence experiments at room temperature showed that under the excitation of 350 nm, complexes 1 and 2 showed strong fluorescence emission at 445 nm and 458 nm, respectively.
