Sulfonated perylene-based conjugated microporous polymer as a high-performance adsorbent for photo-enhanced uranium extraction from seawater

A sulfonated perylene-based adsorbent is prepared for photo-enhanced uranium extraction from seawater. Owing to the photo-enhanced effect, the uranium extraction capacity of PyB-SO₃H in seawater reaches 1989 mg g⁻¹, with 90% extraction efficiency.
