Small-molecular blue phosphorescent dyes for organic light-emitting devices
Organic light-emitting devices (OLEDs) are on the lips of most electronic manufacturers currently. With good progress made in terms of production cost, efficiency and color output, OLEDs have found more applications recently as compared to those some years ago. Because of the possibility of obtaining long-lasting, durable and energy-efficient OLEDs, researchers devote much time and effort towards the improvement of OLED technology and development of advanced OLED products. Blue light-emitting materials, especially blue phosphorescent materials, are indispensable for full-color displays and white OLED lighting. Compared with green and red light-emitting materials and devices, the blue-emitting counterparts show a relatively inferior performance in terms of color purity, luminescence efficiency and device durability. In this perspective article, we highlight the recent progress and current challenges of blue-emitting metallophosphors based on small molecules and their applications in phosphorescent OLEDs. © 2013 The Royal Society of Chemistry and the Centre National de la Recherche Scientifique.
