Controllable assembly of organodisulfonate complexes with tuned mole ratios: From 0D to 3D networks

Four novel organodisulfonate coordination polymers ranging from 0D cluster, 1D chain, 2D layer to 3D framework, {[Eu2(phen)4(nds)2(OH)2(H2O)2]·2H2O}n (1), {[Eu(phen)2(nds)0.5(OH)(H2O)]·0.5nds}n (2), {[Eu2(phen)4(nds)3(H2O)2]·7H2O}n (3), {Eu(phen)(nds)(OH)}n (4) (nds = 2,6-naphthanlenedisulfonate; phen = 1,10-phenanthroline), were synthesized by tuned stoichiometric ratio of the reactants and characterized by single crystal X-ray diffraction, elemental analysis, IR and thermogravimetric analysis. These complexes display a broad and strong ligand-centered luminescent emission band, and all of them have long luminescence lifetimes at millisecond order.
