New pyridopyrazine skelecton-based electron-transporting materials

2,3-Di(pyridine-2-yl)-7-(4-triphenylsilyl)phenyl)pyrido[2,3-b]pyrazine (DPPP) containing pyridopyrazine was designed and synthesized as a new electron-transporting material for organic lightemitting devices (OLEDs). The obtained material forms homogeneous and stable amorphous film. The new synthesized showed the reversible cathodic reduction for hole blocking material and the low reduction potential for electron transporting material in organic EL devices. The molecule possess excellent thermal stability with glass transition temperature (Tg) of 115 °C in nitrogen. DNTPD (60 nm)/NPD (30 nm)/CBP:Irppy 6% (40 nm)/BAlq (10 nm)/ETL (30 nm)/LiF (0.5 nm)/Al structured device were fabricated using DPPP as electron transport material. The maximum luminance reached at 25000 cd/m2. The current efficiency was 10.9 cd/A even high current. Copyright
