These π-conjugated materials are suitable for the preparation of the emissive and charge-transporting layers of organic light-emitting diodes (OLEDs), polytronics, and organic solar cells. The π-conjugated electroluminescent (EL) polymers have been very active due to their fi lm-forming abilities via spin coating and their tunable luminescence properties, which makes them an excellent choice in both singleand multilayer OLEDs. Polymer light-emitting diodes (PLEDs) have many advantages, including self-emission, low operating voltage, fast switching time, easy fabrication at low cost, and potential in full-color fl at-panel displays and fl exible displays compared to other displays.1-3 The effi ciency of the OLEDs is determined by the amount of charge-carrier injection, the probability of charge capture, and the balance between the injection rates of electrons and holes from opposite contacts into the OLEDs.4-6 In simple OLEDs, the emissive layer would be sandwiched between two electrodes. At the cathode, the electrons are injected into the lowest unoccupied molecular orbital (LUMO); at the anode, the holes are injected into the highest occupied molecular orbital (HOMO). The two charges move through the layer under the applied bias and if they meet on the same molecule, they can Book Name: Organic Electronics |
