Abstract

A novel covalent-triazine framework (CTF-PO71) is designed and prepared from an organic pigment molecule for high-performance gas separation. The functional sites with different electrostatic potentials on the pore surface of CTF-PO71 demonstrate a strong interaction between C₂H₂ and CTF-PO71 to achieve preferential adsorption of C₂H₂ over C₂H₄, thus enabling effective capture of a trace amount of C₂H₂ from the gas mixture. This is the first organic porous polymer that is capable of separating C₂H₂ and C₂H₄. The commercial availability and the low cost of the pigment as well as the high stability of the resultant framework endow CTF-PO71 with a significant potential for practical applications.
