Highly Efficient Solution-Processed Green Phosphorescent Organic Light-Emitting Diodes by Employing a New Bipolar Host Material |
| 초록 |
A new bipolar host material (4'-(9H-carbazol-9-yl)-[1,1'-biphenyl]-4-yl)di-o-tolylphosphine oxide (m-CBPPO1) has been designed and synthesized for solution-processed PHOLEDs. m-CBPPO1 consisting of a hole-transporting unit cabazol, biphenyl and an electron-transporting unit phosphine oxide as D-π-A unit. m-CBPPO1 shows good thermal/morphological stability with high Tg (103 oC). The photophysical, and electrochemical properties of the complex was systematically investigated by UV-visible, PL spectra and cyclic voltammetry. In addition, the green PHOLEDs were fabricated with the configuration of ITO/PEDOT:PSS/TCTA:m-CBPPO1:Dopant/TmPyPB/LiF/Al. The optimized PHOLEDs showed maximum current efficiency of 54.85 cd/A, maximum power efficiency of 38.29 lm/W and maximum external quantum efficiency of 15.29%. |
