Abstract

With the Zn-Schiff-base [ZnL(CH ₃CN)] from the Salen-type Schiff-base ligand H ₂L (H ₂L = N,N′-bis(3-methoxy- salicylidene)cyclohexane-1,2-diamine) with the flexible linker as the precursor, a series of hetero-trinuclear Zn ₂Ln complexes [Zn ₂Ln(L) ₂(Cl) ₃] (Ln = Nd, 1; Ln = Yb, 2; Ln = Er, 3; Ln = Gd, 4) are obtained by the further reaction with LnCl ₃·6H ₂O, respectively. The results of their photophysical studies show that the strong and characteristic NIR luminescence with emissive lifetimes in the microsecond range, has been sensitized from the excited state (both ¹LC and ³LC) of the ligand due to the effective intramolecular energy transfer.
