  • Ligand-containing conjugated microporous polymer and use thereof
    Patent number: 10639613
    Abstract: The present invention relates to a ligand-containing conjugated microporous polymer, which is obtained by covalent coupling of a conjugated microporous polymer and a uranium complexing ligand. The conjugated microporous polymer comprises an aromatic ring and/or a heterocyclic ring. The uranium complexing ligand is selected from the group consisting of a compound with a group containing phosphorus, a compound with a group containing nitrogen, and a compound with a group containing sulfur. The invention further provides use of the ligand-containing conjugated microporous polymer as a uranium adsorbent. The ligand-containing conjugated microporous polymer the invention is capable of adsorbing the radioactive element uranium in strongly acidic and strong-radiation environments.
