Abstract

Abstract: To develop highly efficient organic dyes adsorbents are of great importance for environmental issues. In this work, a negatively charged porous organic polymer (POP) is synthesized by simple aromatic nucleophilic substitution (SN Ar) and hydrolysis reaction. This polymer POP‐TFP‐COOH structure is confirmed by IR and 13 C cross‐polarization/magic‐angle‐spinning nuclear magnetic resonance. Due to the existence of phenyl rings and carboxylic acid groups, POP‐TFP‐COOH displays excellent adsorption ability for the positive dye methylene blue (MB), with a maximum value of 2740 mg g −1 . This porous polymer can be reused at least four times without obvious loss of its adsorption capacity. Abstract : In this work, a negatively charged porous organic polymer (POP) is synthesized.
