Abstract

The series of homoleptic tetranuclear [Ln ₄(L) ₂(HL) ₂(NO ₃) ₂(OH) ₂] ·2(NO ₃) (Ln = Nd, 1; Ln = Yb, 2; Ln = Er, 3; Ln = Gd, 4) have been self-assembled from the reaction of the Salen-type Schiff-base ligand H ₂L with Ln(NO ₃) ₃·6H ₂O (Ln = Nd, Yb, Er or Gd), respectively (H ₂L: N,N′-bis(salicylidene) cyclohexane-1,2-diamine). The result of their photophysical properties shows that the strong and characteristic NIR luminescence for complexes 1 and 2 with emissive lifetimes in microsecond ranges are observed and the sensitization arises from the excited state (both ¹LC and ³LC) of the Salen-type Schiff-base ligand with the flexible linker.
