A bisimidazolium-based cationic covalent triazine framework for CO2 capture and dye adsorption

In this work, an aromatic nitrile containing the pyrimidine moiety and bisimidazolium cations (PyImCl) was synthesized and subsequently employed to prepare a bisimidazolium-based cationic covalent triazine framework (PyImCl-cCTF) through the ionothermal trimerization reaction. The chemical composition and structure of PyImCl-cCTF were carefully revealed by a series of techniques. As examined by N2 sorption isotherms at 77 K, PyImCl-cCTF...
