Abstract

© 2021, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.In this study, we synthesized an aliphatic–aromatic regular network as a novel covalent organic networks called TEPN-1 (Thiol-ene Polymer Network) and TEPN-2 via thiol-ene chemistry. TEPN-1 and TEPN-2 were analyzed by FTIR, 13C-NMR, Brunauer–Emmett–Teller, thermogravimetric analysis and elemental analysis. Solvent uptake capacity of TEPN-1 and TEPN-2 was employed against 26 solvents which are frequently used in chemical industry. It is found that TEPN-1 has the highest swelling adsorption ratio with chloroform and DCM (13.7 and 11.5 g.g−1, respectively), while TEPN-2 has 9.2 and 7.5 g.g−1, respectively. Both TEPN-1 and TEPN-2 have very minimal water uptake (0.165 and 0.189 g.g−1, respectively). TEPN-1 and TEPN-2 are efficient adsorbents for most of organic solvents including water-miscible organic solvents such as THF, dioxane and pyridine.
