Abstract
Abstract A binary solvent synthetic strategy is proposed for the construction of C 2 ‐symmetric molecule‐based hydrogen‐bonded organic frameworks (HOFs) with permanent ultra‐micropores and surface polarization derived from tunable coplanar open oxygen atoms. The activated HOFs BTBA‐1 a and PTBA‐1 a show highly selective separation of CO 2 /N 2 with a record high ideal adsorbed solution theory (IAST) selectivity >2000 under ambient temperature and pressure.
