| Popis: | Resumen del trabajo presentado a la X International School on Organometallic Chemistry “Marcial Moreno Mañas”, celebrada en Ciudad Real (España) del 5 al 7 de julio de 2017. The synthesis of Iridium(III) phosphorescent complexes has attracted a lot of attention due to their potential of serving as key components for various optoelectronic applications, such as phosphorescent emitters for organic light-emitting diodes (OLEDS). Among these complexes homoleptic and heteroleptic cyclometalated phenylpyridine derivatives of Ir(III) have been widely studied due to the relatively short lifetime of the triplet excited state, high emission efficiency and tunable emission color. While there are many green and red emitters that meet the requirements of device design, the development of blue phosphorescent emitters remains a challenge. In this context, iridium N-heterocyclic carbene complexes have been considered as ideal triplet emitters, because of their high luminescence quantum yield, color purity and stability imparted by the strong Ir-C(NHC) bond. In this communication, we describe the synthesis of a new family of neutral heteroleptic Ir(III) complexes bearing N-heterocyclic ligands which are emissive in the bluegreen region and have high quantum yields. |
