The field of organic light emitting diodes (OLEDs) has been developed in the areas of solid-state lighting, large size and flexible displays. As emitting compound, phosphorescent materials can harvest both single and triplet excitons for light, enabling internal quantum efficiency of 100%. In particular, iridium complexes have been very successful as phosphorescent emitters, especially for green and red emissions, because of their high photoluminescent efficiency and short excited life time. However, development of high efficiency, especially deep-blue emitting phosphorescent materials has been a significant challenge for high performance of full color displays and white OLEDs. Therefore, there is a lot of work to find iridium complex that has both blue emission and high EQE in OLEDs. In this work, we designed and synthesized two heptafluorosulfonyl substituted Iridium complexes with perfluoro-sulfonyl group (SOCF7pic and SOCF7mpic) for blue phosphorescence organic light emitting diodes (PHOLEDs).
