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.

在这项研究中，我们通过硫醇-烯化学合成了一种脂肪族-芳香族规则网络，作为一种新型共价有机网络，称为 TEPN-1（硫醇-烯聚合物网络）和 TEPN-2。TEPN-1 和 TEPN-2 通过 FTIR、¹³ C-NMR、Brunauer-Emmett-Teller、热重分析和元素分析进行​​分析。TEPN-1 和 TEPN-2 的溶剂吸收能力被用来对抗化学工业中常用的 26 种溶剂。发现TEPN-1 对氯仿和DCM 的溶胀吸附率最高（分别为13.7 和11.5 gg ^-1），而TEPN-2分别为9.2 和7.5 gg ^-1。TEPN-1 和 TEPN-2 的吸水量都非常小（0.165 和 0.189 gg ^-1， 分别）。TEPN-1 和 TEPN-2 是大多数有机溶剂的高效吸附剂，包括可与水混溶的有机溶剂，如四氢呋喃、二恶烷和吡啶。
