Intrigued by the high porosity and chemical stability of BDP-TFP-COF, we performed adsorption experiments in aqueous media. As model compounds for water remediation, the common micropollutant bisphenol A (BPA) and the widespread water-soluble dye methylene blue (MB) were selected for adsorption and removal studies. Heterogeneous adsorption experiments at 298 K revealed a very high BPA uptake at low COF concentration with 97% BPA being removed from a 100 ppm aqueous solution at 1.0 g L -1 BDP-TFP-COF dosage (see Section 3 of the SI for experimental and analytical details). The adsorption process could be modelled according to both Langmuir and Freundlich isotherms (Figure and Table ). Both models indicate a favorable adsorption process with a theoretical maximum adsorption capacity of 425.53 mg g -1 of BPA into the BDP-TFP-COF pores. This very high uptake is among the highest reported for COFs and COF composites so far (Table ) and reveals a remarkable performance in the removal of BPA from H2O.
