This talk will review the molecular and electronic properties of the guests and hosts used in the active emissive layers in molecular organic light-emitting devices (MOLEDs), and the electrical and luminescent characteristics of MOLEDs with high efficiency, good thermal stability and extended lifetime. Saturated red, green and blue (RGB) emission based on a common host will be discussed in terms of energy transfer from the host to the guest molecules, and direct electron-hole recombination on the highly luminescent guest molecules. The mechanisms leading to high electroluminescence quantum efficiency and, good thermal and temporal stability will be discussed.
