Poly(9,9-dioctylfluorene) based hyperbranched copolymers with three balanced emission colors for solution-processable hybrid white polymer light-emitting devices
The white-light hyperbranched copolymers with triple emitting units were designed and synthesized. These copolymers have shown high fluorescence quantum efficiency. A high color rendering index (CRI) of 87 and a Commission International de l'Eclairage coordinate of (0.31, 0.33) were achieved.
