The efficient removal of trace carcinogenic organic pollutants, such as polycyclic aromatic hydrocarbons
(PAHs) and ionic dyes, from water is an important technical challenge. We report a highly effective
recyclable multifunctional azobenzene (AZ)-based silica-supported polymeric adsorbent which can
simultaneously remove both PAHs and anionic dyes from water to below parts per billion (ppb) level based
on multiple interactions such as the hydrophobic effect, [pi]–[pi] stacking and electrostatic interactions, thus
providing a new strategy for designer water remediation materials.
