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…
Iridium(III) Complexes with Phenyl-tetrazoles as Cyclometalating Ligands
Ir(II) cationic complexes with cyclometalating tetrazolate ligands were prepared for the first time, following a two-step strategy based on (i) a silver-assisted cyclometalation reaction of a tetrazole derivative with IrCl3 affording a bis-cyclometalated solvato-complex P ([Ir(ptrz)(2)(CH3CN)(2)](+), Hptrz = 2-methyl-5-phenyl-2H-tetrazole); (ii) a substitution reaction with five neutral ancillary ligands to get [Ir(ptrz)(2)L](+), with L = 2,2'-bypiridine (1), 4,4'-di-tert-butyl-2,2'-bipyridine (2), 1,10-phenanthroline (3), and 2-(1-phenyl-1H-1,2,3-triazol-4-yl)pyridine (4), and [Ir(ptrz)(2)L-2](+), with L = tertbutyl isocyanide (5). X-ray crystal structures of P, 2, and 3 were solved. Elect…
Anionic Cyclometalated Iridium(III) Complexes with a Bis-Tetrazolate Ancillary Ligand for Light-Emitting Electrochemical Cells
none 10 si A series of monoanionic Ir(III) complexes (2-4) of general formula [Ir(C^N)2(b-trz)](TBA) are presented, where C^N indicates three different cyclometallating ligands (Hppy = 2-phenylpyridine; Hdfppy = 2-(2,4-difluoro-phenyl)pyridine; Hpqu = 2-methyl-3-phenylquinoxaline), b-trz is a bis-tetrazolate anionic N^N chelator (H2b-trz = di(1H-tetrazol-5-yl)methane), and TBA = tetrabutylammonium. 2-4 are prepared in good yields by means of the reaction of the suitable b-trz bidentate ligand with the desired iridium(III) precursor. The chelating nature of the ancillary ligand, thanks to an optimized structure and geometry, improves the stability of the complexes, which have been fully char…
