Abstract

Two multiaryl-substituted pyridine derivatives, applied as electron transport materials (ETMs; see figure) with good holeblocking ability in high-performance deep-blue organic light-emitting diodes (OLEDs), are characterized. The maximum current efficiencies of the devices based on the new compounds are over 70% higher than previously reported devices using traditional ETMs instead. The CIE coordinates of the devices based on the new compounds are close to the NTSC standards of (0.14, 0.08) for blue emission. " Chemical equation presented" © 2010 WILEY-VCH Verlag GmbH & Co.
