Abstract
Multiheterostructure electroluminescence (EL) devices with blue emission color based on parahexaphenyl (PHP) as the emitting layer and various new organic materials as hole and/or electron transport layers (HTL, ETL) were fabricated to improve the EL efficiency. We present new ETLs, which were prepared via different metal-catalyzed coupling reactions of brominated educts in high yields. Utilizing these new organic materials enables us to obtain high performance of blue PHP EL devices with low threshold fields (0.3 MV/cm) and high external EL quantum efficiencies up to 3.4%.
