  Luminescence and structural studies of yttrium and heavier lanthanide–picrate complexes with pentaethylene glycol

  摘要：

  The monoclinic structural isomers with molecular formula of [M(Pic)(2)(EO5)](Pic) where EO5 = pentaethylene glycol, Pic = picrate anion, and M = Gd, Tb, Er, Tm, Yb, and Y have been synthesized and characterized. The current study was conducted in the solid state to evaluate the coordination pattern of the central metal ion with the EO5 ligand in the presence of Pic anion. The photoluminescence (PL) spectra of the Tb and Yb complexes have the typical 4f-4f transition emissions of Tb(III) and Yb(III) ions. The Gd, Er, Tm, and Y complexes had broad bands resulting from the ligands. The counteranion factor influenced the emission intensity in the Tb-Pic-EO5 and Tb-NO3-EO5 complexes in several solvents also were studied. The Pic anion acts as a quencher in the [Tb(Pic)(2)(EO5)](Pic) complex due to the nitro withdrawing groups was clearly observed both in solution and the solid state. (C) 2009 Elsevier B. V.
