| 英文摘要 | a series of blue-emitting poly(spirobifluorene)s (psfs), namely, cz-psf, 4ro-psf and dpa-psf, have been designed and synthesized by incorporating 2,7-bis(3,6-di-tert-butyl-9h-carbazol-9-yl)-9h-fluorene (czf), 2,3,6,7-tetraoctyloxyfluorene (4rof) and n, n', n'', n'''-tetrakis(4-butylphenyl)-9h-fluorene-2,7-diamine (dpaf) as their electron-rich side chains, respectively. consistent with their measured homo levels (czf: -5.40 ev; 4rof: -5.17 ev; dpaf: -4.86 ev), the donor strength of the pendant is enhanced in the sequence czf < 4rof < dpaf. as a result, the charge transfer (ct) effect from the pendant to the backbone is found to be gradually intensified on going from cz-psf to 4ro-psf and dpa-psf. the emission maximum is accordingly red-shifted from 423 nm for cz-psf to 452 nm for 4ro-psf and 482 nm for dpa-psf, which is associated with a significant decrease in the photoluminescent quantum yields. compared with 4ro-psf, the copolymer cz-psf containing a weaker donor shows deep-blue emission with cie coordinates of (0.16, 0.09-0.12) and a peak luminous efficiency of 2.21 cd a(-1). these results indicate that the ct effect can be effectively tuned to realize high-performance deep-blue-emitting psfs by the manipulation of the electron-donating ability of their spiro-conjugated side chains. |
