 Covalent Triazine Frameworks (CTFs) are a new type of porous semi-crystalline polymers, which are constructed with organic building units via strong covalent bonds, displaying great potential applications in adsorption, catalysis, gas storage and high efficient separation. In this research, CTF Membranes were prepared from 4,4’-biphenyldicarbonitrile via a sol-gel route. The successful formation of triazine rings in the as-synthesized CTF membranes were proved by Fourier Transform infrared spectroscopy (FTIR) and Solid-state 13C Nuclear Magnetic Resonance (ssNMR). Based on the above results, the permeation behavior of different organic solvent through the CTF membranes were systematically investigated. The permeability of mono alcohols through the CTF membranes increases with the carbon numbers of the alcohols and decreases with the increasing numbers of branch chain of the alcohols. In addition, it was found that the permeability of organic solvent increases with its octanol-water partition coefficient (Kow). This work demonstrates the potential applications of CTF membranes for organic solvent separation.
