Functional materials for various organic electronic devices

Since the discovery of conductivity in organic molecules in the 1980s, the field of organic electronics has witnessed immense advancement. The main reason for such growth is the possibility of designing and developing innumerable functional organic materials. Today, almost all possible optoelectronic applications have been developed using various organic materials, and many of them have been commercialized for use in day to day lives of common people. This chapter summarizes a series of functional organic materials used in high efficiency solar cell devices, bright light emitting diodes (LEDs), high mobility and high ON/OFF ratio field effect transistors (FETs) and resistive random access memory (ReRAM) devices for switching applications. This chapter will be a guide to further improve the properties of functional organic materials for better performances in future.
