| Abstract | Through an approach of pre-coordination and following terpolymerization from vinyl-functionalized complex monomers [Ln(TTA)3(4-VB-PBI)] (Ln 1⁄4 Eu, 2; Ln 1⁄4 Tb, 3 and Ln 1⁄4 Gd, 4; HTTA 1⁄4 2thenoyltrifluoroacetonate; 4-VB-PBI 1⁄4 1-(4-vinylbenzyl)-2-(pyridin-2-yl)-1H-benzo[d]imidazole) with methyl methacrylate, the first example of a single-component Eu–Tb–Gd-grafted polymer Poly(MMA-co-2-co-3-co-4) was obtained. Moreover, control of an optimal dye content for suppressing Tb to Eu energy transfer and exciton formation provides new perspectives for hetero-Ln-grafted polymers as featured in Poly(MMA-co-2-co-3-co-4) with color-tuning to direct white-light (Commission International De L'Eclairage coordinates of x 1⁄4 0.322, y 1⁄4 0.331; corrected color temperature of 5979 K; and color rendering index up to 94), including a highly luminous efficiency of 17.8%. |
