Three new anthracene cored molecules, AP3Py-Na, AP3Py-2Na and ADP3Py were designed and synthesized to use as an efficiency enhancement layer (EEL) in blue fluorescent organic light emitting diodes (OLEDs). Insertion of a very thin EEL (3 nm) between the deep blue the electron transport layer (ETL) and emitting layer (EML) improved the external quantum efficiency (EQE) of the blue device by 44% compared to the device without the EEL, resulting in external quantum efficiency of 7.9% and a current efficiency of 9.0 cd/A at 1,000 cd/m2.
