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.
