The advent of porous polymers capable of both CO2 capture and conversion is an emerging research area to tackle ever-increasing CO2 emissions into the atmosphere and also to use CO2 as a sustainable C1 source. Porous cationic polymers, which are analogous to zeolites, with exchangeable counteranions offer ideal platform for the simultaneous capture and conversion of CO2. Here, we report on the porous cationic polymers (Ru-PCPs) with increased number of charges synthesized through condensation reaction between tris(1,10-phenanthroline-5,6-dione)Ru(II) dichloride and ortho-aromatic amines in AlCl3 at 400 degrees C. Ru-PCPs exhibited surface areas up to 526 m(2) g(-1) and CO2 uptake capacities as high as 3.76 mmol g(-1), which is among the highest reported to date for porous cationic polymers. The high CO2-philicity of Ru-PCPs originating from the presence of multiple charges and nitrogen sites coupled with the nucleophilic Cl- anions rendered Ru-PCPs as highly efficient heterogeneous catalysts for the conversion of CO2 and propylene oxide to propylene carbonate through atom economy reaction. Notably, unlike previously reported porous cationic organocatalysts which require CO2 pressures of 10-30 bar, Ru-PCPs were shown to operate efficiently even under atmospheric pressure of CO2 mainly arising from the increased number of charges and counteranions.
