Synthesis of ligand 4,4’-(1h,1’h-5,5’-bibenzo[d]imidazol-2,2’-diyl)dibenzoic acid: a new linker for MOFs

Abstract

A novel ligand 4,4’-(1H,1’H-5,5’-bibenzo[D]imidazol-2,2’-diyl)dibenzoic acid, was synthesized and fully characterized by various spectroscopic methods such FT-IR, ¹H, ¹³C-NMR and DEPT analysis. MOFs material derived from this ligand and zinc nitrate has been synthesized by solvothermal method. The structure of the new MOFs was examined by powder XRD, thermogravimetric analysis (TGA) and the nitrogen physical uptake reveal the surface area based on Langmuir theory is up to 147 m²/g.
