Abstract
With the [Zn(HL) 2(Py)] compound from the benzimidazole-based ligand H 2L (H 2L: 2-(1H-benzo[d]imidazol-2-yl)-6- methoxyohenol) as the precursor, the series of four hetero-binuclear ZnLn arrayed complexes [ZnLn(HL) 2(Py)(NO 3) 3] (Ln = Nd, 1; Ln = Yb, 2; Ln = Er, 3; Ln = Gd, 4) have been obtained by the further reaction with Ln(NO 3) 3·6H 2O, respectively. The result of their photophysical properties shows that the strong and characteristic NIR luminescence of Nd 3 + or Yb 3 + ion with emissive lifetimes in microsecond range, has been sensitized from the excited state ( 1LC and 3LC) of the benzimidazole-based ligand. © 2012 Elsevier B.V.
