title: Selective binding and reversible release of riboflavin by polymer-bound zinc(II) azamacrocycles.
abstract: The reversible formation of a coordinative bond between a polymer-bound Lewis-acidic metal complex and a flavin imide moiety allows complete extraction of riboflavin from aqueous solution at physiological pH and its quantitative release at pH 5.
