Through terpolymerization of vinyl-functionalized complex monomers 2-3 ([Zn(L)(4-vinyl-Py)Ln(BA)2(NO3)] (Ln = Eu, 2 or Ln = Tb, 3; H2L = N,N′-bis(salicylidene)cyclohexane-1,2-diamine; 4-vinyl-Py = 4-vinyl-pyridine; HBA = 1-phenyl-1,3-butanedione) with dual emissions, and/or blue-light-compensatory [Zn(L)(4-vinyl-Py)Gd(BA)2(NO3) (4) with MMA (methyl methacrylate), we offer a robust pathway to single-component while heterometallic-containing metallpolymer-type hybrid materials with color-tunable white-light as featured like Zn2+-Eu3+-Tb3+-containing Poly(2-co-MMA-co-3) and Zn2+-Eu3+-Tb3+-Gd3+-containing Poly(MMA-co-2-co-3-co-4). Moreover, by a strategy to control of optimal dye contents for managing Tb3+ to Eu3+ energy transfer and excimer formation, their intrinsic white-light emissions can be easily optimized from a precise control of primary-chromophore content and excitation wavelength, rendering both a highly luminous efficiency (15.6%) and an excellent color-quality (CIE (Commission International De L'Eclairage) coordinates of 0.334–0.344, 0.332–0.355; CCTs (corrected color temperature) of 5051–5404 K and ultra-high CRIs (color rendering index) up to 87-91) with potentials for future color-critical high-level applications.
