The invention provides UV-sensitive monomers, comprising a cyclopropenone-containing group, which acts as a masked dibenzocyclooctyne (DBCO)/dibenzoazocyclooctyne (DIBAC) group. The monomers of the invention can be polymerized for example via reversible addition fragmentation chain transfer (RAFT) polymerization techniques to yield a polymer comprising the masked DBCO/DIBAC group. In certain embodiments, the DBCO/DIBAC group can be unmasked under controlled conditions, allowing conjugation of small molecules and/or macromolecules to the polymer through highly selective and efficient strain-promoted azide alkyne click chemistry (SPAAC).

A fiber comprising a carbon chain backbone and amidoxime, carboxylate, and nitrile pendant groups. The fiber may be used for removing uranium from seawater and toxic metals from drinking water.
