• Through terpolymerization of the red-light complex monomer [Eu(tta) 3 (4-vp-2,2′bpy)] ( 2 ; Htta = 2-thenoyltrifluoroacetone; 4-vp-2,2′-bpy = 2-(pyridin-2-yl)-5-(4-vinylphenyl)pyridine), blue-green-light complex monomer [Zn(L)(4-vinyl-Py)Gd(NO 3 ) 3 ] ( 8 ; Salen-type H 2 L = N , N ′-bis(3-methoxy-salicylidene)phenylene-1,2-diamine; 4-vinyl-Py = 4-vinyl-pyridine) with MMA (methyl methacrylate), the obtained Eu 3+ -Zn 2+ -Gd 3+ -containing metallopolymer Poly(2- co -MMA- co -8) (120 : 1[ 2 / 8 = 2 : 1 or 1 : 2]) exhibits stoichiometry-dependent color-tuning photoluminescence due to effective Zn 2+ -Gd 3+ -Salen to Eu 3+ energy transfer. Moreover, using them as the corresponding emitting layers, a high color-purity red-light polymer light-emitting diode (PLED) with a luminous efficiency of 0.037 lm W −1 and first-example Ln 3+ -containing-metallopolymer-based WPLED with an eternal quantum yield of 0.003% is realized. With color-tunable Eu 3+ -Zn 2+ -Gd 3+ -containing metallopolymer Poly(2- co -MMA- co -8) as the emitting layer, bright color-purity red-light PLED to first-example Ln 3+ -containing-metallopolymer-based WPLED were realized.
