- The construction of efficient adsorption materials for the removal of pollutants from water is of primary importance for environmental protection. Here, we present a novel cationic porous organic polymer C-NSANₐₚₕHCP@Br, that features a permanent porosity with a high surface area and moderate pore volume, and exhibits excellent chemical stability. More importantly, the new cationic network was found to be an excellent platform for the removal of anionic organic dyes and Cr₂O₇²⁻ from water with rapid adsorption rates, excellent selectivity and high efficiency, as well as good recyclability.
