Considerable efforts have been devoted to realize efficient electron injection in polymer light-emitting diodes (PLEDs) for better charge balance and higher efficiencies. Efficient electron injection can be achieved through interfacial engineering such as modification of electrodes using self-assembled monolayers and introduction of polymer interlayer. The focus of this paper is to review the materials, device structures and performance of PLEDs incorporating polymer interlayers.
