Readily synthesised arylamino fumaronitrile for non-doped red organic light-emitting diodes

Bright (maximum 10034 cd m(-2), 455 cd m(-2) at 20 mA cm(-2)) and efficient (maximum 2.4% at 4 mA cm(-2)) red (lambda(max)el 634-636 nm) organic light-emitting diodes employ arylamino-substituted fumaronitrile as the novel host emitter, which is readily prepared and easily purified.

High Performance Host Materials of Electrophosphorescence Blue Dopants

SimCP is a superior host material to mCP for phosphorescent blue dopant of OLEDs. Triphenylsilyl substituent plays a critical role in preventing molecules from aggregation and hence maintaining high triplet-state energy in condense phase. Article not available.

61.3: Blue Dopants and New Host Materials for Phosphorescent Organic Light‐Emitting Diodes

In this paper, we describe two new blue phosphorescent dopant materials FIrtaz and FIrN4. Efficient organic light-emitting diodes(OLEDs) incorporating demonstrate higher-purity blue-lightemission than the long-known FIrpic phosphorophore. New host material SimCP with higher glass-transition temperatures were also found to enhance the blue phosphorescence OLED performance.
