The present disclosure provides compositions, methods, and devices for sensing, detecting, and/or selectively capturing phosphate from water. An exemplary method includes: contacting a ligand or a rare earth metal complex of a ligand as described herein with an aqueous phosphate-containing medium at a pH of 5 to 12 under conditions sufficient to bind phosphate (e.g., reversibly bind phosphate). In certain embodiments, the method further includes releasing the bound phosphate by contacting the bound phosphate complex with an aqueous medium at a pH of 0 to 4 under conditions sufficient to release the bound phosphate.
