ChemInform Abstract: Luminescent Ionic Transition Metal Complexes for Light-Emitting Electrochemical Cells

Higher efficiency in the end-use of energy requires substantial progress in lighting concepts. All the technologies under development are based on solid-state electroluminescent materials and belong to the general area of solid-state lighting (SSL). The two main technologies being developed in SSL are light-emitting diodes (LEDs) and organic light-emitting diodes (OLEDs), but in recent years, light-emitting electrochemical cells (LECs) have emerged as an alternative option. The luminescent materials in LECs are either luminescent polymers together with ionic salts or ionic species, such as ionic transition-metal complexes (iTMCs). Cyclometalated complexes of IrIII are by far the most utiliz…

Lumineszierende ionische Übergangsmetallkomplexe für leuchtende elektrochemische Zellen

Durch die Umsetzung neuer Beleuchtungskonzepte konnte die Verwertung von Energie deutlich effizienter gestaltet werden. Alle derzeit entwickelten Technologien beruhen auf elektrolumineszierenden Festkorpern und lassen sich allgemein als Festkorperbeleuchtung (solid-state lighting, SSL) einstufen. Die beiden wichtigsten Zweige der SSL-Technologie sind Leuchtdioden (LEDs) und organische Leuchtdioden (OLEDs), doch seit kurzem bilden auch leuchtende elektrochemische Zellen (LECs) eine Alternative, die als aktive Materialien entweder lumineszierende Polymere in Kombination mit ionischen Salzen oder lumineszierende ionische Spezies wie ionische Ubergangsmetallkomplexe (iTMCs) enthalten. Cyclometa…
