Schiff Bases and Their Complexes in Organic Light Emitting Diode Application

Optoelectronics is an active area of research and, for few decades, development of different semiconducting materials with a wide emission window has attracted researchers. Organic light emitting diodes (OLEDs) are primarily utilized in displays and light sources that greatly contribute towards the conservation of energy and do not need a backlight for displays. Development in device efficiency, lifetime and stability is now a major concern in this particular application, and designing efficient material for OLEDs has been an active field of research for decades. Metal-organic compounds possess different optical and electronic properties due to metal and organic ligand interactions which are primarily used in OLEDs. This review is mainly focused on the Schiff bases and their metal chelates as a pure emitting layer or as a dopant material for the fabrication of R/G/B/white emitting devices. Moreover, future prospects to explore further to advance research in the OLED arena are also discussed. [GRAPHICS] .
