title: A stable, pillar-layer metal-organic framework containing uncoordinated carboxyl groups for separation of transition metal ions.
abstract: A 3D pillar-layer framework (1) with uncoordinated carboxyl groups exhibits exceptional stability. It can effectively and selectively adsorb Cu(2+) ions and has been applied as a chromatographic column for separating Cu(2+)/Co(2+) ions.
