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.
