摘要：
A series of linear and X-shaped oligo(para-phenylene) derivatives functionalized with fluorene ethynylenes 1, 3 and 4 were synthesized through sequent Sonogashira coupling and Suzuki-Miyaura reaction in high yield. The electron-donating group -OCH3 and electron-withdrawing counterparts -CF3 were introduced to tune the spectra properties of compounds 3 and 4. The detail investigation of their photophysical properties in solution and film indicated that the introduction of both -OCH3 and -CF3 makes maximum emission distinct red-shift in comparison with parent compound 1, but the latter more prominently.
