High-capacity and rapid adsorption of organic micropollutants (OMPs) from water by adsorbents remain a great significance in water treatment. Recently, porous organic polymers with high surface areas, tunable nanopores and easy-to-modify skeletons are promising new generation of adsorbents. Here, a series of silsesquioxane-crosslinked conjugated microporous polymers (PcCMPs) with high surface areas and well-defined nanopores are developed via a molecular expansion strategy for removing OMPs from water. Among these PcCMPs, PcCMP-2E exhibited the highest Brunauer-Emmett-Teller surface area up to 2518 m(2) g(-1). The maximum adsorption capacities of bisphenol A (BPA) of PcCMPs are ranging from 485.44 to 628.93 mg g(-1). Specially, > 93.5% of BPA could be removed even through a thin layer filtration device composed of PcCMPs, which can be regenerated well using a mild washing procedure. PcCMPs also exhibit extraordinary adsorption to a variety of OMPs, such as tetracycline (226.99 mg g(-1)), 1naphthylamine (290.07 mg g(-1)), 2-naphthol (213.87 mg g(-1)), 2,4-dichlorophenol (183.85 mg g(-1)) and p-nitrophenol (360.24 mg g(-1)). This work provides a new strategy to design porous adsorbents with high adsorption capacity and fast adsorption rate for water treatment. (C)& nbsp;2022 Elsevier Inc. All rights reserved.
