A light‐emitting polymer with simultaneous blue (λ max = 445 nm), green (λ max = 515 nm), and red light (λ max = 624 nm) emission for bias‐independent white electroluminescence is reported (see Figure). The polymer is synthesized by covalently attaching a green‐light‐emissive and a red‐light‐emissive chromophore to a macromolecule with blue‐light emission. White‐light color coordinates of (0.31, 0.34) and a luminance efficiency of 1.59 cd A –1 are obtained.
