Luminescent zinc and cadmium metal-organic frameworks based on tetrazole ligands

Abstract Three metal-organic frameworks with 1D zigzag chain [Zn(dte)(H 2 O) 3 ]·2H 2 O ( 1) , 2D double layer [Cd(dtb)(H 2 O)(phen)] ( 2 ), 3D network [Zn(dte)(phen)] ( 3 ) based on tetrazole-based ligands (H 2 dtb = 1,3-dis(2H-tetrazol-5-yl)benzene, H 2 dte = 1,4-ditetrazolylethylene, phen = 1,10-phenanthroline), have been synthesized and characterized. All the compounds exhibit unusual strong luminescence at room temperature in the solid state and can be potentially used as luminescent materials.
