| 英文摘要 | instead of conjugated dibenzothiophene-s,s-dioxide (dbtso), we have introduced nonconjugated diphenylsulfone (dpso) as the electron-deficient unit into the main chain of poly(spirobifluorene)s (psfs). because of the weaker electron affinity of dpso relative to dbtso, the charge transfer from the pendant 2,3,6,7-tetraoctyloxyfluorene to the main chain can be effectively prevented. consequently, the resultant polymers containing dpso moiety show pure blue emissions, which is different from dbtso-based psfs that exhibit undesired green emissions. with a single-layer device configuration, a peak luminous efficiency of 2.90 cd/a and a maximum luminescence of 14130 cd/m(2) have been realized for the polymer psfdpso03. the corresponding cie coordinates are (0.17, 0.18), nearly independent of the applied current density from 2 to 592 ma/cm(2). these results indicate that tuning the electron affinity of the incorporated electron-deficient units is a very promising strategy to control the charge transfer strength for the development of blue-emitting psfs with high efficiency and stability |
