摘要：
Through doping or grafting of a new ZnNd Schiff-base complex monomer [Zn(L)(4-vinyl-Py)Nd(NO3)(3)] (2; H2L = N,N'-bis(3-methoxy-salicylidene)phenylene-1,2-diamine; 4-vinyl-Py = 4-vinyl-pyridine) into PMMA (poly(methyl methacrylate)), two kinds of hybrid materials 2@PMMA and Poly(2-co-MMA) with significantly improved physical properties including good Nd3+ -centered near-infrared (NIR) luminescence were obtained. Especially the single-nodal ZnNd-grafted Poly(2-co-MMA) soluble in organic solvents exhibits the high sensitization efficiency (eta(sens) = Phi(L)(Nd)/Phi(Nd)(Nd) = 81%) even at a high feed molar ratio up to 1:50.
