“…The efficiencies of WOLED based on Os-3 climbed up to 40.4 cd/A and 25.6 lm/W when it was doped with blue phosphor FIrpic [54]. Shu, Chi, and Chou synthesized a series of electrophosphorescent copolymers, in which a red-emitting Os(II) complex was embedded in the backbone of polyfluorene, giving a highly efficient PLED with maximum η ext of 18.0 % and maximum brightness of 38,000 cd/m 2 with an emission centered at 618 nm [55]. Furthermore, through covalent attachment of a low concentration of a green-emitting benzothiadiazole unit in the same polymers, efficient WOLED with η L of 10.7 cd/A and η ext of 5.4 % was achieved.…”

With the rapid growth of population and urbanization, the energy demand is increasing annually. Due to the major problems concerning the rapid depleting nature of the extraction of fossil resources, energy conservation and transition to renewable energy supplies have been a hot topic worldwide. Organic light-emitting diodes and solar cells represent two important techniques to allow the efficient utilization of energy resources in energy-saving devices and exploration of using renewable energy in energy-producing devices. In this chapter, the importance of using organometallic and organic molecules in both areas of research is discussed.

White organic light emitting diodes (WOLEDs) have gained considerable attention of academic and industrial research communities as promising alternative to incandescent lamps, fluorescent tubes and inorganic LEDs for low energy consumption lighting applications. WOLEDs are expected to become one of the next generation lighting sources because of their high color tunability and color quality, which can be easily achieved by proper chemical design of organic electroluminescent materials. Contrary to their inorganic counterparts, WOLEDs also bear the distinctive feature of being available as flexible and large area devices. Over the last decades, a lot of efforts have been spent on defining suitable strategies to highly efficient WOLEDs based on the use of properly tailored organic emitters. Here we survey the main chemical approaches to white electroluminescence from organic light emitting materials, highlighting strong and weak points of each strategy. Current research on new hybrid white light emitting devices based on the combination of inorganic LEDs and organic down color converters is also reviewed by some representative examples.
