DBPP (2,5‐di‐(2‐biphenyl)‐1,4‐phenylene) units were embedded into a PPV (poly(p‐phenylenevinylene)) backbone, resulting in a dramatic improvement in the solid‐state photoluminescence quantum efficiency of the polymer. Oxadiazole units were introduced as PPV main‐chain substitutents, imparting the resulting polymer with bipolar charge‐transporting properties. A carefully‐designed conjugated polymer combining both DBPP and oxadiazole units showed both high PL efficiency and bipolar charge transport ability, making it a promising candidate for the fabrication of efficient single‐layer LED devices.
