46DCzPPm, bipolar host or hole blocking material
High purity (>99% sublimed) 46DCzPPm available in quantities from 250 mg to 1 g
Like 26DCzPPy, 46DCzPPm (also know as CzPhPy) has a bipolar structure with two electron rich end carbazole units attached to an electron deficient biphenylpyrimidine center unit. It has one extra nitrogen unit than 26DCzPPy.
46DCzPPm is normally used as bipolar host material for blue, red and green phosphorescent OLED devices. An extremely low driving voltage of 3.9 V was achieved using 46DCzPPm as the bipolar host material, and FIrPic as the blue triplet emitter. In the device, an n-doping electron-transport layer consisting of Cs2CO3-doped 46DCzPPm and a p-doping hole-transport layer consisting of MoO3-doped 46DCzPPm were constructed [2].
With a deep HOMO energy level (6.19 eV), 46DCzPPm can also be employed as an efficient hole blocking layer material.
