Single-nodal linking for Zn2+-Nd3+-containing metallopolymer with efficient near-infrared (NIR) luminescence

Through the single-nodal copolymerization of MMA (methyl methacrylate) and a vinyl-containing complex monomer [Zn(L)(4-vinyl-Py)Nd(NO3)3] (2; H2L = N,N′-bis(3-methoxy-salicylidene)ethylene-1,2-diamine; 4-vinyl-Py = 4-vinyl-pyridine) with the both 1π-π* and 3π-π* sensitizing approach to Nd3 + ion, the Zn2 +-Nd3 +-containing metallopolymer Poly(MMA-co-2) exhibits good physical properties including an attractive Nd3 +-centered NIR sensitization efficiency (ΦLNd = 1.22% and η = ΦLNd/ΦNdNd = 82%).
