Inside Cover: Phosphorescent Cyclometalated Iridium(III) Complexes That Contain Substituted 2‐Acetylbenzo[b]thiophen‐3‐olate Ligand for Red Organic Light‐Emitting Devices (Chem. Asian J. 12/2014)

Abstract

workers report on the preparation of a new class of bis-cyclometalated iridium (III) complexes of substituted 2-acetylbenzo[b]thiophen-3-olate (bt) ligands exhibiting orange to infrared emissions. Highly efficient organic light-emitting diodes (OLEDs) based on the iridium (III) complexes as dopant (emitter) and commercially available hosts exhibit stable red emission that matches well with the National Television System Committee (NTSC) standard with CIE chromaticity coordinates of (0.67, 0.33) have been fabricated.
