Abstract

Conjugated microporous polymers (CMPs) have demonstrated significant potential for gas separation due to their permanent microporosity

high adsorption capacity

and exceptional chemical robustness. However

the scalable

cost-effective and environmentally friendly synthesis of CMPs as an alternative to energy-intensive traditional solvothermal methods remains underexplored. Herein

we present a solvent-free

flux synthesis method for constructing olefin-linked amorphous CMPs (NKCMP-1 and NKCMP-2) through Knoevenagel condensation of 2

6-tetramethylpyrazine with linear aromatic aldehydes. This method surpasses ion

othermal and mechanochemical routes in terms of scalability and product uniformity. Notably

NKCMP-1 can be synthesized on a kilogram scale (0.54 kg) while maintaining structural integrity

high surface area and a uniform microporous architecture. Both NKCMP-1 and NKCMP-2 exhibit outstanding C

/CO

selectivity and cyclic stability under ambient conditions

as confirmed by dynamic breakthrough experiments. These features make the developed CMPs highly promising for real-world industrial gas purification applications.
