Blue Phosphorescent Organic Light-Emitting Diodes Based on SFX2PO Host

Abstract:

We report on blue phosphorescent organic light-emitting diodes (PHOLEDs) with biphenyl (Spiro[ﬂuorene-9,9′-xanthen]-2-yl) phosphine oxide（SFX2PO）host. The device studied in this work has the structure of ITO/m-MTDATA:MoOx(10nm)/m-MTDATA(30nm)/ TAPC(10nm)/SFX2PO: Firpic(10nm)/Bphen(40nm)/LiF(1nm)/Al(200nm), in which maximum luminance of 8950 cd/m2 and power efﬁciency of14.65 lm/w have been achieved.
