Abstract

A fully solution-processed deep-blue emitting organic light emitting diode (OLED) based on a highly efficient fluorescent dendritic material with a pyrene core, a phenylene shell and triphenylamine surface groups coupled with polymeric hole (HTL) and electron (ETL) transport layers is demonstrated. Each layer formed smooth and pinhole-free films as demonstrated by Atomic Force Microscopy (AFM) as well as by X-ray Photoelectron Spectroscopy (XPS). Furthermore, detailed Ultraviolet Photoelectron Spectroscopy (UPS) surveys revealed a beneficial energy level alignment and hence improved charge carrier confinement. The resulting triple-layer device saw a 7.7-fold increase in current efficiency compared to a single-layer device while maintaining a deep-blue emission color characterized by the CIE1931 coordinates of x = 0.153 and y = 0.155.
