锌(II)配位聚合物的自组装由于其有趣的骨架和荧光特性而引起了人们的强烈兴趣。两种具有 pcu 网络的新型 3D ZnII 配位聚合物，由 [Zn2L1L2(mbtz)]·H2O (1) 和 [Zn4L12L22(btp)2]·7H2O (2) 配制而成 [H2L1 = 2,5-二苯甲酰对苯二甲酸，H2L2 = 4,6-二苯甲酰间苯二甲酸，mbtz = 1,3-双(1,2,4-三唑-1-基甲基)苯和btp = 1,3-双(1,2,4-三唑-1-基)丙烷]在正常水热条件下合成。单晶 X 射线衍射分析表明，这两种化合物都表现出有趣的 3D pcu 框架，并显示出由 ZnII 和 N-供体配体之间的配位化学引起的荧光发射变化。
Self-assembly of zinc(II) coordination polymers have attracted intense interests due to their intriguing frameworks and fluorescence properties. Two new 3D ZnII coordination polymers with pcu networks, formulated by [Zn2L1L2(mbtz)]·H2O (1) and [Zn4L12L22(btp)2]·7H2O (2) [H2L1 = 2,5-dibenzoylterephthalic acid, H2L2 = 4,6-dibenzoylisophthalic acid, mbtz = 1,3-bis(1,2,4-triazol-1-ylmethyl)benzene, and btp = 1,3-bis(1,2,4-triazol-1-yl)propane], were synthesized under normal hydrothermal conditions. Single-crystal X-ray diffraction analyses revealed that both of the two compounds exhibited interesting 3D pcu frameworks, and showed shifted fluorescent emissions arising from the coordination chemistry between ZnII and the N-donor ligands.
