Abstract

With the Zn-Schiff-base [ZnL(CH₃CN)] from the pure Salen-type Schiff-base ligand H₂L (H₂L = N,N′-bis(salicylidene) phenylene-1,2-diamine) as the precursor, a hetero-trinuclear Zn₂Nd complex [Zn₂Nd(L)₂(NO₃)₃(CH ₃CN)₂] (1) and a hetero-binuclear ZnNd complex [ZnNd(L)₂Cl(DMF)] (2) are obtained by the further reaction with Nd(NO₃)₃•6H₂O or NdCl₃• 6H₂O, respectively. The influence of structural differences of the two complexes on their photophysical properties shows the anionic inducement leads to the effective modulation of the NIR luminescent properties by the adjustment of the coordination sphere of the Nd³⁺ ions.
