제목 Development of New Fluorescent Emitters Based on Coumarin Moiety
초록 Py-An-Cu, Cu-An-Cu, An-Cu, and Na-Cu were synthesized through Suzuki aryl-aryl coupling reaction. Optical properties were evaluated by UV-visible absorption and photoluminescence (PL) spectra. In film state, Py-An-Cu, Cu-An-Cu, An-Cu, and Na-Cu exhibited UV-Visible absorption band in the range of 334nm~403nm. Also, in film state, four materials exhibited PL peaks in the range of 426nm~506nm. Synthesized compounds were used as an emitting layer (EML) in non-doped device with the following structures: ITO/2-TNATA (60 nm)/NPB (15 nm)/synthesized compounds (35 nm)/Alq3 (20 nm)/LiF (1 nm)/Al (200 nm). Non-doped devices showed luminance efficiency (L.E.) of 1.38, 1.03, 1.12, and 0.39 cd/A at a current density of 10 mA/cm2.
