Abstract

A rigid macrocyclic phthalocyanine-based porous polymer, CPP, was synthesized by a one pot "click" reaction between tetraazido-phthalocyanine and bisamine diethynylbenzene. This CPP is the first example of a phthalocyanine porous polymer used for CO₂ adsorption and it shows very high CO₂ adsorption (15.7 wt% at 273 K/1 bar) and high selectivity for CO₂/N₂ (94) and for CO₂/CH₄ (12.8) at 273 K/1 bar. The CPP exhibited a Brunauer-Emmett-Teller (BET) surface area of 579 m² g^-1 and high thermal stability up to 500 °C, thus showing good potential for CO₂ capture.
