Blue phosphorescent organic light-emitting diodes based on SFX2PO host

摘要：

　　We report on blue phosphorescent organic light-emitting diodes (PHOLEDs) with biphenyl (Spirofluorene-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 of 14.65 lm/w have been achieved.
