Polymer light-emitting diodes (PLEDs) have been the subject of intense research interests recently due to their applications in large-area flat panel displays. To achieve highly efficient PLED devices, charge (holes and electrons) injection and transport from both the anode and the cathode should be balanced at the junction of the emitting layer to yield the maximum exciton formation. Usually, in order to balance charges of injection and transport, most of multilayer PLEDs were fabricated, which involve complicated and difficult device fabrication processes. So, it is important to achieve conjugated polymers which have good hole-transporting or electron-transporting ability, instead of HTL or ETL in multilayer PLEDs. Here, we synthesized some polymers containing hole-transporting or electron-transporting moiety. Their electronic and optical properties will be investigated by different methods. The PLEDs based on copolymers will be fabricated and further compared. |
