Abstract
In this study, a novel porphyrin-based metal–organic framework (Co-Por MOF) was successfully synthesized by a simple one-step solvothermal method. We report a metal–organic framework based on the covalent interaction of an organic linker, 5,10,15,20-tetrakis(4-carboxyphenyl) porphyrin (TCPP) with cobalt clusters. The properties of this material were analyzed by powder X-ray diffraction (XRD), ultraviolet visible adsorption spectroscopy (UV–Vis), Fourier-transform infrared spectroscopy (FTIR), and differential reflectance spectroscopy (DRS).

We report the synthesis, and characterization of a new porphyrin-based MOF obtained from the reaction of 5,10,15,20-tetrakis(4-Carboxyphenyl) porphyrin with cobalt nitrate under solvothermal conditions. (Scheme 1)
UV-visible absorption spectra of tetrakis(4carboxyphenyl) porphyrin (TCPP) ligands were determined by a double beam ultraviolet visible adsorption spectroscopy (UV–Vis) spectrophotometer (Shimadzu UV-1700, Tokyo, Japan)
Summary
Metal–organic frameworks (MOFs) have attracted significant attention as a new class of porous materials, developed in the last two decades. They have unique properties as permanently microporous materials. Linker modification is one of the most direct methods for MOF functionalization Porphyrinic ligands are such a category of versatile linkers that have been extensively explored [12,13]. Synthesis of Co-Por MOF from a TCPP ligand and Co(NO3)2.6H2O This novel porous material can be applied as a heterogeneous photocatalyst that exhibits efficient CO2 photochemical reduction under visible-light irradiation, by cooperating with the porphyrin moiety photosensitizer
