53‐1: Invited Paper: Deuteration of OLED Materials: Impact on Device Performance and Commercial Manufacturing
Elvira Montenegro, Stephanie Ganss, Marcel Bürger, Camille Correia, Aaron Lackner, Sebastian Stolz, Jonas Kröber, Anna Hayer, Jens Engelhart, Rouven Linge, Won-Kyung Na, Su-Hwan NaRecently deuteration has become a key technology for enhancing lifetime of OLED materials without affecting other performance parameters like efficiency and voltage. Over the past years, we intensively investigated the impact of the deuteration degree and pattern on the device performance. The focus of our investigation was triplet matrix materials (TMMs) in the emissive layer and the electron‐blocking layer (EBL). In this paper, we will discuss various aspects of the deuteration of OLED materials: from driving further performance improvements to scale‐up processes.
