Microwave-assisted reductive homocoupling of aromatic nitro monomers: synthesis of azo-linked porous organic polymers for CO₂ capture.

ABSTRACT: An optimized protocol for the rapid synthesis of azo-linked porous organic polymers (POPs) containing trigonal triphenylpyridine (AZO-P-M), triphenyltriazine (AZO-T-M), and tetragonal tetraphenylethylene (AZO-E-M) central units by microwave-assisted NaBH₄-mediated reductive homocoupling of the corresponding aromatic nitro monomers is presented. The structural and functional features of the azo-linked polymers prepared under microwave heating were directly compared to their counterparts obtained by conventional synthesis. Similar to azo-linked polymers synthesized by conventional reductive homocoupling of nitro monomers with NaBH₄, the polymers prepared under microwave irradiation are amorphous solids of good thermal stability showing moderate (e.g., AZO-E-M wit
