Facile synthesis of azo-linked porous organic frameworks via reductive homocoupling for selective CO2 capture†
Abstract
A facile Zn-induced reductive homocoupling reaction was used to synthesize azo-linked porous organic frameworks (azo-POFs) from easily accessed nitro monomers. Azo-POF-2 exhibits the highest CO2/N2 selectivity of 76 at 273 K among all self-coupled azo-linked porous polymers.
