White-Emission PLEDs based on Hyperbranched Polymers |
| 초록 |
Polymeric light-emitting diodes (PLEDs) based on polymers has the advantages of solution processing and tunable emission color through molecular design, which are important requirements for large-area display devices. Herein, we produced a series of single copolymer with hyperbranched polymer (HB) architecture. We ameliorated the morphologies of the thin films and avoid crystallization. In addition, their three-dimensional (3D) structures assist in reducing the aggregation between the conjugated polymers. We investigated multicolor emitting conjugated polymers via incorporating fluorophores into polymer chain. These polymers have a poly(p-phenylene) backbone containing green and red emitting exciton trap sites. We used exciton migration phenomenon for realization of multicolor emission. And we established alkoxy side chain on phenylene backbone to ameliorate solubility. Besides, we verified the EL properties of the polymers by fabrication of the EL device with these polymers. |
