Abstract

Higher efficiency in the end-use of energy requires substantialprogress in lighting concepts. All the technologies under developmentare based on solid-state electroluminescent materials and belong to thegeneral area of solid-state lighting (SSL). The two main technologiesbeing developed in SSL are light-emitting diodes (LEDs) and organiclight-emitting diodes (OLEDs), but in recent years, light-emittingelectrochemical cells (LECs) have emerged as an alternative option.The luminescent materials in LECs are either luminescent polymerstogether with ionic salts or ionic species, such as ionic transition-metalcomplexes (iTMCs). Cyclometalated complexes of IrIII are by far themost utilized class of iTMCs in LECs. Herein, we show how thesecomplexes can be prepared and discuss their unique electronic,photophysical, and photochemical properties. Finally, the progress inthe performance of iTMCs based LECs, in terms of turn-on time,stability, efficiency, and color is presented.
