摘要：

A novel porphyrin-based metal-organic framework (MPF-3) Was synthesized by the solvothermal reaction of Zn(NO3)(2)center dot 6H(2)O and meso-tetra(3-pyridyl)porphine in N,N'-dimethylformamide (DMF). Its structure was characterized by single crystal X-ray diffraction and found to be it two-dimensional (2D) interdigitated framework in which DMF solvent molecules reside between the interdigitated layers. The observed 2D topology can be related to the Cairo pentagonal tessellation. X-ray powder diffraction reveals that MPF-3 undergoes a phase transformation when the solvent molecules arc removed by heating. Surprisingly, the original topologies are restored when the desolvated phase is immersed in DMF, thereby demonstrating the flexibility of the framework.
