A light-emitting polymer with simultaneous blue (lambda(max)=445 nm), green (lambda(max)=515 nm), and red light (lambda(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.
