Highly Efficient and Color‐Stable Deep‐Blue Organic Light‐Emitting Diodes Based on a Solution‐Processible Dendrimer

Abstract

A color-stable blue organic light-emitting diode is obtained utilizing a solution-processible fluorescent π-conjugated dendrimerG0 (see image), with a maximum luminance efficiency of 5.3 cd A−1. Efficient green, red, and white OLEDs are also demonstrated by doping G0 with phosphorescent dyes. Combining high device efficiency with solution processibility, G0 becomes one of the best blue-emitting materials for fabricating flat-panel displays and white-light lighting panels via solution processing.
