Organic Light‐Emitting Devices Red to infrared phosphorescent materials are difficult to achieve. In their Full Paper on page 3572 ff., featured on the Inside Cover, Shiu‐Lun Lai, Sharon Lai‐Fung Chan, Chi‐Ming Che and co‐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.
