제목 Improving the performance of blue-emissive Ir(III) complexs for Solution- Processed Phosphorescent Organic Light-Emitting Diodes using New Bipolar Type Host
초록 Bipolar type host were designed to enhance the maximize recombination efficiency with high triplet energy (ET) for solution processed blue Phosphorescent organic light-emitting diodes (PhOLEDs). donor-π-acceptor (D-π-A) type bipolar host (4'-(9H-carbazol-9-yl)-2,2’-dimethyl-[1,1'-biphenyl]-4-yl)diphenylphosphine oxide (m-CBPPO) were synthesized. The photophysical, thermal and electrochemical properties of the complex was systematically investigated by UV-visible, PL spectra and cyclic voltammetry. The consist of blue PHOLEDs were ITO/PEDOT:PSS/TCTA:m-CBPPO:FIrpic/TSPO1/SPPO13/LiF/Al. The optimized device showed external quantum efficiency of 20.7% and current efficiency of 40.1 cd A-1 with CIE coordinates (0.154,0.322).
