Synergistic experimental and computational investigation of azo-linked porphyrin-based porous organic polymers for CO₂ capture.

ABSTRACT: We synthesized a series of azo-linked porphyrin-based porous organic polymers (APPs) with linear, bent, and trigonal linkers (APP-1 to APP-6) and with directly connected tetraphenylporphyrin units (APP-7a, APP-7b and APP-8). The synthesized APPs are amorphous solids demonstrating good thermal stability and diverse BET surface areas. APPs with linkers showed significantly higher surface areas (469 to 608 m² g^-1) compared to those with directly connected tetraphenylporphyrin units (0.3 to 23 m² g^-1). Higher surface areas correlated with enhanced CO₂ adsorption, particularly for APP-1, APP-2, and APP-5 with experimental CO₂ uptake values of 41 mg g^-1, 38 mg g^-1, and 38 mg g^-1, respectively, at 3
