Through the radical copolymerization of MMA (methyl methacrylate) with a vinyl-containing complex monomer {[Yb4(L)2(HL)23-OH)2(NO3)2]·(NO3)2} (1; H2L = N,N'’-bis-(5-(3'-vinylphenyl)-3-methoxy-salicylidene)cyclohexane-1,2-diamine), the first example of PMMA-supported and Yb4(Salen)4-containing metallopolymer Poly(1-co-MMA) exhibits significantly improved physical properties besides relatively higher NIR quantum yields (ΦYbYb = 1.18% and ΦLYb = 0.86%) than those (ΦYbYb = 1.02–1.04% and ΦLYb = 0.73–0.75%) of complex monomer 1 in solution and 1@PMMA in solid state.
