Electrically Doped PEDOT:PSS Electrodes for the Application in Organic Light-Emitting Diodes |
| 초록 |
A facile way to enhance electrical conductivity of conductive polymers via solution-processed low-concentration doping, is suggested. An organic cationic azo dye was used as a p-type dopant for poly(3, 4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) to realize highly conductive electrodes for organic light-emitting diode (OLED) applications. By optimization of the dopant concentration, the doped PEDOT:PSS films exhibited electrical conductivities enhanced from 16.2 S•cm-1 to 226.7 S•cm-1, more than an order of magnitude. UV-vis absorption spectroscopy studies indicate that charge transfer complexes between PEDOT:PSS and dopant were successfully formed and the dopant exhibits high tendency to oxidize the polymer in a single-blend system for efficient doping. We propose a simple and low-cost doping agent to improve conductivity and sheet resistance of PEDOT:PSS to be applied as a promising electrode material for various kinds of highly flexible organic devices. |
