Abstract
Abstract Starting from the transition metal salts and mixed organic ligands of 4,4′-{[1,2-phenylenebis-(methylene)]bis(oxy)}dibenzoic acid (H 2 L) and different N-containing linkers, six new coordination polymers, [Cd(L)(2,2′-bipy)] n ( 1 ); [Cu(L)(2,2′-bipy)] n ( 2 ); {[Zn(L)(4,4′-bipy)][Zn(L)(H 2 O)]} n ( 3 ); [Cu(L)(4,4′-bipy) 0.5 (H 2 O)] n ( 4 ), [Zn 2 (L) 2 (bpp)] n ( 5 ) and [Cd 3 (L) 2 (OAc) 2 (Him) 2 ] n ( 6 ) (2,2′-bipy = 2,2′-bipyridine, 4,4′-bpy = 4,4′-bipyridine and bpp = 1,3-bis(4-pyridyl)propane), were synthesized and characterized. The structural differences of 1 – 6 indicate the effect of the auxiliary N-donor ligands and nature of metal centers could modulate the resulting architectures. The photoluminescent sensing behaviours of 1 and 5 toward Cu 2+ cation and nitro explosives have been investigated in detail. Interestingly, the immobilized Cu 2+ cation can be easily separated by ethylenediaminetetraacetic acid (EDTA).
