Synthesis of covalent organic framework and it’s potential applications

Abstract

In this project, our target is to synthesize a pristine, stable bis-benzothiazole linked covalent organic framework (COF) via a one pot synthesis. Out of the two monomers required, 2,5-diamino-1,4-benzenedithiol dihydrochloride (DABT) is available commercially. The other monomer, [1,1':4',1''-terphenyl]-3,3'',5,5''-tetracarbaldehyde (TPTC) is synthesized by employing Suzuki-Miyaura cross-coupling reaction. The synthesized compound is characterized using 1H and 13C NMR spectroscopy. The COP is synthesized further by varying the reaction conditions and characterized by FT-IR, PXRD, FE-SEM, TGA and BET analysis. The chemical stability of our synthesized TBBTCOP was checked in different solvents. Further we also performed a post-synthetic modification on our COP by incorporating copper into it and utilized it for Chan-Lam coupling reaction between various substrates.
