Five rare earth-indole carboxylic acid complexes: [Eu(IAA)(2)(phen)(2)]center dot NO3 (1) (IAA = indole acetic acid, phen = o-phenanthroline); [Nd(IAA)(2)(phen)(2)]center dot NO3 (2); [Er(IBA)(3)(phen)](phen)center dot HNO3 center dot H2O (3) (IBA = indole butyric acid); [Ce(IBA)(3)(phen)](phen)center dot HNO3 center dot H2O (4); [Dy(IBA)(3)(phen)](phen)center dot HNO3 center dot H2O (5) were synthesized and characterized. Then, we reported their properties as dye adsorption and fluorescence sensing for the first time. The fluorescence explorations demonstrated that complex 1 exhibits highly selective and sensitive sensing for nitro aromatic compounds with high sensitivity (1.49 x 10(7) M-1) and low detection limit (11.40 A mu M). Meanwhile, these complexes also exhibit stronger selective adsorption of dye molecules (MB and MG) in aqueous solution. This study provides new physical insights into the rational design of lanthanide complexes based on multifunctional materials. @@@ We firstly reported five lanthanide complexes and displayed fluorescence sensing and selective adsorption dye properties. @@@ [GRAPHICS] @@@ .
