【Abstract】

A new two-dimensional (2D) bio-metal-organic framework based on trinuclear cluster units,[Zn_3(adeninate)_2(CH_3COO)_4]·DMF (Zn–A),was synthesized by the self-assembly of biomolecule adenines with zinc ions.Topological analysis reveals its 4~4 connected layer structure.Remarkably,Zn–A bears high sensitivity and selectivity detection ability of iron ion with the limit of detection being 4.0×10~(-6) mol/L.
