Molecular LED: Design Concept of Molecular Materials for High-Performance OLED

  • Chapter
Organic Light-Emitting Devices

Abstract

The recent rapid development of organic light-emitting diodes (OLEDs) has resulted in the commercialization of simple dot-matrix OLED displays.1 The great success of OLED devices has also introduced a brand new organic semiconductor. Now, we are in the process of designing the physical and chemical makeup of this new type of organic semiconductor. In this chapter, first we will briefly describe the OLED development from the 1960s to the 1980s. Second, we will define the new organic semiconductor especially utilized for OLED devices and clarify what the organic semiconductor is and how it differs from the conventional inorganic semiconductor. Then, we will review the recent OLED progress by taking the following aspects into consideration: the design of multilayer cell structures, the design of each molecular constituents, hole transport, electron transport, and emitter and dopant molecules. Finally, we will discuss the future prospects of OLEDs.
