Synthesis and Characterization of Novel Crosslinkable Poly(propylenedioxythiophene) Derivative as a Buffer Layer for Organic Light-Emitting Diode Applications |
| 초록 |
A new crosslinkable polythiophene derivative, poly(hexynyl2-PDOT-co-heptyl2-PDOT), with (PDOT) moiety containing solubilizing and crosslinkable substitutents as a pendant group were synthesized by oxidative polymerization using FeCl3. The resulting copolymer was soluble in organic solvents and spun cast onto the indium tin oxide (ITO) coated glass substrate to make a uniform thin film. We fabricated organic light-emitting diodes (OLEDs) in ITO/buffer layer/MEH-PPV/LiF/Ca/Al configuration using either PEDOT:PSS or poly(hexynyl2-PDOT-co-heptyl2-PDOT) as a buffer layers. Due to the intrinsic conductivity of poly(hexynyl2-PDOT-co-heptyl2-PDOT) than that of PEDOT:PSS caused the decreasing OLED performance. The turn-on voltage of the OLED using poly(hexynyl2-PDOT-co-heptyl2-PDOT) buffer layer was observed 5 V. The maximum brightness and luminance efficiency were 2,597 cd/m2 at 12 V and 0.3 cd/A, respectively. |
