Synthesis and Photoelectronic Properties of Novel High-efficiency Bipolar Phosphorescent Host Material
H NMR. DMIC-PmPCP was used as host material for bis(2-methyl-6-phenylpyridine)(2-([1
1'-biphenyl]-3-yl)pyridine)iridium (GD-01) in fabricating high efficiency phosphorescent organic light emitting diode(OLED). The device gave a green emission with CIE coordinate of (0.33
0.62) and maximum current efficiency of 70.16 cd·A
-1
was obtained. It also exhibits high current efficiency of 55.08 cd·A
-1
at luminance of 3 000 cd·m
-2
which is about 17.4% more than the current efficiency of similar structural OLED with 1
3-dihydro-3
3-di-methyl-1-(3-(4
6-diphenyl-1

5-triazin-2-yl)phenyl) indane[2
1-b]carbazole(DMIC-TRZ) as the host material. DMIC-PmPCP was also used as host material for Tri(2-phenylpyridine)iridium(Ir(PPy)
3
) in fabricating green PhOLED
the device exhibited high current efficiency of 52.33 cd·A

at luminance of 3 000 cd·m
-2
. The more balanced carrier transport plays a key role for excellent device performance and making DMIC-PmPCP a promising candidate as the host material for green PhOLEDs.
