【摘要】 通过Stille偶合反应合成了2,7位二噻吩基取代的新型芴类衍生物并首次应用固相聚合法合成出聚-2,7-二噻吩基芴。在25℃测得聚合物的特性粘度为0.68dl/g。通过棱磁共振(~1H-NMR)、红外光谱(FTIR)对单体和聚合物的结构进行了表征确认,同时研究了聚合物的光学、结晶态形貌及热学性能。研究发现,2,7-二噻吩基芴在研磨过程中发生了聚合反应且其偶合发生在e,e′位置。

【Abstract】 A novel fluorene derivative 2,7-dithiophen-fluorene has been synthesized by coupling of 2,7-dibromo- fluorene and 2-(tributylstannyl)-thiophene via Stille reaction.The corresponding polymer poly(2,7-dithiophen- fluorene)was synthesized by one-step solid-state reaction at room temperature,and the intrinc viscosity,of which in DMF is 0.68dL/g at 25℃.To our knowledge,it’s the first time to prepare fluorene-based conjugated polymers using this polymerization method by nowadays.The chemical structure of monomer and polymer was verified by ~1H-NMR,FT-IR and elemental analysis,and the ~1H-NMR and FT-IR results showed that polymeri- zation was happened at the e,e′-positions of 2,7-dithiophen-fluorene.The optical,crystallization state and ther- modynamic properties of polymer were also investigated here.
