Synthesis and Characterization of pure-phase Zr-MOFs Based on meso-Tetra(4-carboxyphenyl)porphine
Chapter 1: The unique chemical and biological properties of porphyrins have led to increased interest in the development of porphyrin-based materials. Metal organic frameworks (MOFs) can act as a scaffold for the immobilization of porphyrins in desired arrangements. The crystalline nature of MOFs …
