1)  bipyrazole
联吡唑
1.
This thesis focuses on the Cu~I or Zn~II d~(10) metal complexes based on bipyrazole, and then proposes some new methods and thoughts in the self-assembly of poly-dimensional structures and controlled design of functional coordination compounds through pre-designing the secondary building units as the structural and functional carriers.
本文主要通过联吡唑配体的功能性设计,制备了一系列基于联吡唑配体的Cu~Ⅰ/Zn~Ⅱ配位聚合物,并深入探讨了如何通过设计二级建筑单元(SBU)作为结构和性质的载体来实现目标配合物的构筑,以及第二配体对整个自组装过程的影响,以期实现超分子的合成从完全盲目的自组装逐步走向有目的的自组装,并对目标配合物的结构与部分性质进行了研究,为潜在的应用提供了可能。
