Light-emitting properties of polyfluorene copolymers containing N-alkoxyphenylphenothiazine. |
| 초록 |
Random copolymers of 9,9-diethylhexylfuorene and N-(2-ethylhexyloxy) phenylphenotiazine, poly(BEHF-co-APPTZ)s, were synthesized through Ni(0) mediated polymerization. Light-emitting devices were fabricated using these polymers in an ITO (indium-tin oxide)/PEDOT:PSS/polymer/Ca/Al configuration. Each EL device constructed with a poly(BEHF-co-APPTZ)s copolymer exhibited significantly enhanced efficiency and brightness compared to devices constructed from and PBEHF homopolymers. This enhanced efficiency of the copolymer devices results from their improved hole injection and more efficient charge carrier balance, which arise due to the HOMO levels of the poly(BEHF-co-APPTZ)s copolymers, which are lower than that of the PBEHF homopolymer. Synthesis and light-emitting properties of those polymers will be presented. |
