The high surface area and the functionalities of the COF catalyst act synergistically to activate the starting material. The 2,3-DhaTph shows excellent activity towards cyclic carbonates at the atmospheric pressure of carbon dioxide. Additionally, this catalytic system is recyclable in nature and provides a higher turnover number than previously reported organocatalysts.1 aSaptal, Vitthal1 aShinde, Digambar, Balaji1 aBanerjee, Rahul1 aBhanage, Bhalchandra, M.  uhttps://library.ncl.res.in/content/state-art-catechol-porphyrin-cof-catalyst-chemical-fixation-carbon-dioxide-cyclic-carbonates
