Toxic volatile organic compounds (VOCs) such as BTEXs (i.e., benzene, toluene, ethylbenzene, and xylenes), formaldehydes and chlorinated hydrocarbons, emitted from industrial chemical processes and outdoor or indoor chemical applications are harmful to environment and threat to human health. Removal and recovery of VOCs from air with porous adsorbents like zeolites, activated carbon and its derivatives, and MOFs has been widely studied and confirmed as an effective technique. However, porous organic polymers (POPs) which gain much interest during last decade as an alternative stable material for gas adoption/separation is rarely studied with VOCs. Herein, we have designed and synthesized Hexaphenylbenzene (HPB) and Hexabenzocoronene (HBC)-based POPs and studied their adsorption of organic vapors. Our HPB-based POP selectively adsorbs aromatic vapors with a superior capacity (99.9 wt. %) whereas HBC-based POP shows simultaneous high adsorption capacities towards both aliphatic and aromatic vapors (51.7 and 53.0 wt. %).
