a FT-IR of pristine membrane fabricated at various temperatures (35–145 °C). The disappearance of –NH2 bands between 3200 and 3400 cm−1 and the shift of C=O from 1643 to 1609 cm−1 has been shown in the insets. b XRD of COF membranes (assembled at 145 °C) from TFP–PDA pristine membranes pre-assembled at various temperatures.
