Highly Tunable Heterometallic Frameworks Constructed from Paddle-Wheel Units and Metalloporphyrins

Seven new heterometallic frameworks have been synthesized with specific control over the metallic composition of each structure. Using Mn, Fe, Ni, V, and Pt metallated tetra-(4-carboxyphenyl)porphine (MTCPP) metalloligands and Zn and Co paddle-wheel building units, two series of heterometallic frameworks are assembled that maintain topology with changing metal composition.

本研究通过精准调控每种结构的金属组成，成功合成了七种新型杂金属骨架（heterometallic framework）。以锰（Mn）、铁（Fe）、镍（Ni）、钒（V）及铂（Pt）金属化四(4-羧基苯基)卟啉（metallated tetra-(4-carboxyphenyl)porphine, MTCPP）作为金属配体，搭配锌（Zn）与钴（Co）的桨轮型构筑单元，成功组装得到两类杂金属骨架；该类骨架在金属组分发生变化时，仍可维持其固有拓扑结构。
