| 제목 | Alkoxyphenyl-substituted polyfluorene: A stable blue-light-emitting polymer with good solution processibility |
| 초록 | The development of new materials displaying colors correctly with high efficiency and stability is essential for the development of a full-color display. Poly(fluorene)s (PFs) are promising new materials for blue-light-emitting diodes because of their high photoluminescence quantum efficiency, thermal stability, and also easy color tuning by introducing low-band-gap comonomers. However, the emission of long-wavelength radiation by polymer films comprising PFs upon heating during device formation or operation has been the crucial problem for practical applications. In the study reported here, we introduced alkoxyphenyl groups on the 9-position of fluorene to suppress the additional long-wavelength emissions. An alkoxyphenyl-substituted PF, poly[9,9-bis(4’-n-octyloxyphenyl)fluorene-2,7-diyl] (PBOPF), has been synthesized as a blue-light-emitting polymer with high color purity and good solubility, and its light-emitting properties have been characterized. |
