title: Arsenate recognition in aqueous media by a simple tripodal urea.
abstract: The environmentally important and toxic arsenate anion (HAsO4(2-)) is trapped in the cavity of a dimeric capsular assembly formed by a tripodal urea receptor. The selective binding of HAsO4(2-) over other anions is observed in a semi-aqueous solvent using a (1)H NMR titration study.
