A binary solvent synthetic strategy is proposed to construct molecule-based hydrogen-bonded organic frameworks (HOFs) with permanent ultra-micropores and surface polarization. The activated HOFs showed highly selective separation of CO2/N-2 under ambient temperature and pressure, making them potentially useful for gas separation applications.
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 CO2/N-2 with a record high ideal adsorbed solution theory (IAST) selectivity >2000 under ambient temperature and pressure.
