Abstract

The first examples of Wolf Type II Zn₂Ln-containing metallopolymers poly{MMA-co-[Zn₂(L)₂(4-vp) ₂Ln(NO₃)₃]} (Ln = La, Nd, Yb, Er, Gd; H ₂L = N,N′-bis(salicylidene)ethylene-1,2-diamine; 4-vp = 4-vinylpyridine; MMA = methyl methacrylate) are obtained from the controlled copolymerization of heterotrinuclear Zn₂Ln-arrayed complexes [Zn ₂(L)₂(4-vp)₂Ln(NO₃)₃] (Ln = La, 1; Ln = Nd, 2; Ln = Yb, 3; Ln = Er, 4; Ln = Gd, 5) with MMA. The strong and characteristic near-infrared (NIR) luminescent Ln³⁺-centered emission for each of the PMMA-supported poly{MMA-co-[Zn₂(L) ₂(4-vp)₂Ln(NO₃)₃]} (Ln = Nd, Yb, Er) hybrid materials is retained with somewhat higher intrinsic quantum yields than those of the respective Zn₂Ln-arrayed complex. Especially for poly(MMA-co-3), which has more efficient sensitization from both ligand-centered singlet (¹LC) and triplet (³LC) states of the chromophores, the concentration self-quenching of Yb³⁺-based NIR luminescence could be effectively prevented. The first examples of Wolf Type II near-infrared-luminescent Zn₂Ln-containing metallopolymers poly{MMA-co-[Zn₂(L)₂(4-vp)₂Ln(NO ₃)₃]} (H₂L = N,N′-bis(salicylidene) ethylene-1,2-diamine; Ln = La, Nd, Yb, Er, Gd; MMA = methyl methacrylate; 4-vp = 4-vinylpridine) are obtained from the controlled copolymerization of MMA with a series of Zn₂Ln-arrayed Schiff base complexes [Zn ₂(L)₂(4-vp)₂Ln(NO₃)₃].
