Readily synthesised arylamino fumaronitrile for non-doped red organic light-emitting diodes
Abstract
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 (λmaxel 634–636 nm) organic light-emitting diodes employ arylamino-substituted fumaronitrile as the novel host emitter, which is readily prepared and easily purified.
