Abstract: | The reaction of Ln(NO3)2·6H2O salts (Ln = Eu and Tb) with an excess of 2-fluorobenzoic acid (H-2FBz) in an ethanol/water mixture allows the isolation of dinuclear compounds with the formula [Ln2(μ2-2FBz)4(2FBz)2(H-2FBz)2(H2O)2] (Ln = Eu (1) and Tb (2), 2FBz = 2-fluorobenzoate). A solid-state photoluminescence study of complexes 1 and 2 shows the 4f-4f lanthanide transitions in the visible range with improved emission quantum yields. 1 and 2 are water soluble and photoluminescence studies have also been performed in water and D2O solutions, showing that the emission due to the 4f-4f electronic transitions is still present. The magnetic behaviors of 1 and 2 are also reported. |
