| Abstract | A series of blue light-emitting copolymers containing alternative dialkoxy-substituted phenylene group and the fluorene moiety with different functional groups at the C-9 bridge position have been prepared through the Suzuki polymerization in this contribution. The detailed investigation of the optical properties demonstrates that the spectral thermal and optical stability of P1-3 exhibit substantially enhanced resistance to both thermally and optically oxidation by the backbone modification strategy. Moreover, in comparison with P1 and P3, P2 with the spiro-junction shows much higher Tg and significantly improves resistance towards oxidation in the air, indicating that the spiro-junction is a better strategy to prevent the formation of ketonic defects or the migration of the exicitons to these defect sites. These properties have established our desired polymers as a family of promising candidate for optoelectronic applications. |
