| Abstract: | A series of novel acridine derivatives （1-4） with 1H-phenanthro9,10-d]imidazol-2-yl（PTI） substitutional group have been designed and synthesized. Their photophysical, electrochemical, thermal, photoluminescence （PL） and electroluminescence （EL） properties have been investigated. The photo induced energy transfer behavior of these compounds in doped films has been studied. These compounds were used as emitter to fabricate organic light-emitting diodes （OLEDs）, which exhibited green-yellow emission. The 1-4 based OLEDs showed the low turn-on voltage （2.4 V）, and high power efficiency （13.3 lm/W）, which represents high EL performance based on the simple HTL-EML-ETL device architecture with fluorescent organic molecule as emitters. |
