a Optical photographs of the free-standing TpPa-COF-5% and TpPa-COF-1% membranes. b Photographs showing the TpPa-COF-10% membrane, which has a diameter of up to ~9 cm, with a quarter dollar coin (24.26 mm in diameter) as a reference. c Photographs showing the TpPa-COF-10% membrane with a thickness of up to 1.01 mm. d Schematic illustration of creating TpBZ-COF-10% and TpPa-CO2H-COF-10% membranes. e Experimental PXRD patterns of TpBZ-COF-10% and TpPa-CO2H-COF-10% membranes. f N2 sorption isotherms collected at 77 K for TpBZ-COF-10% and TpPa-CO2H-COF-10% membranes, the BET surface areas were calculated as 821 and 135 m2 g−1, respectively.
