Abstract The solvothermal synthesis of three new 2D MOFs is reported. From the reaction of 3,5-di(1H-imidazol-1-yl)pyridine (dip) and the metal salts Co(NO3)2·6H2O, Cd(NO3)2·4H2O or Zn(NO3)2·4H2O, the three MOFs [Co(dip)2(SCN)2] (1), {[Cd(dip)2(H2O)2]·(NO3)2} (2), {[Zn(dip)2(H2O)2]·(ClO4)2} (3) were obtained. For these 2D MOFs, all the metal ions adopt a six-coordinate octahedral geometry with axial coordination sites occupied by SCN− or water molecules. The SCN−/water ligands were all mono-coordinate and led to layered MOF structures. Furthermore, the fluorescence properties of 2 and 3 have been investigated.

基于3,5-二(1H-咪唑-1-基)吡啶的二维配位聚合物及其荧光特性

摘要 报道了三种新型二维 MOF 的溶剂热合成。由 3,5-二(1H-咪唑-1-基)吡啶 (dip) 与金属盐 Co(NO3)2·6H2O、Cd(NO3)2·4H2O 或 Zn(NO3)2·4H2O 反应，三个 MOFs [Co(dip)2(SCN)2] (1), {[Cd(dip)2(H2O)2]·(NO3)2} (2), {[Zn(dip)2(H2O)得到2]·(ClO4)2}(3)。对于这些 2D MOF，所有金属离子都采用六坐标八面体几何形状，轴向配位点由 SCN-或水分子占据。SCN-/水配体都是单配位的并导致分层的MOF结构。此外，还研究了 2 和 3 的荧光特性。
