Since the discovery of efficient organic light-emitting diodes (OLEDs) based on low-molecular-weight compounds and conjugated polymers, significant progress in materials and device science has led to the realization of full-color OLEDs with improved efficiencies and lifetimes. The stability of green OLEDs containing Alq3 has been extensively investigated. In contrast, the stability of blue OLEDs has remained largely unexplored. While many classes of blue-light emitters have been developed, the device lifetimes for most of the materials have not been reported to date. Several anthracene derivatives have been demonstrated for use in efficient blue OLEDs with promising stability. Nevertheless, the reported lifetimes are poor compared to those of state-of-the-art green and red OLEDs. In this paper, we report on the design, synthesis, and characterization of blue-light-emitting meterials with a naphtylanthracene unit.
