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。 The novel 2,7-thienyl-substituted fluorene derivatives were synthesized by Stille coupling reaction and poly-2,7-dithienylfluorene was synthesized by solid state polymerization for the first time. The intrinsic viscosity of the polymer measured at 25 ° C was 0.68 dl / g. The structures of the monomers and polymers were characterized and confirmed by ~ 1H-NMR and FTIR. The optical, crystalline morphologies and thermal properties of the polymers were also studied. It was found that 2,7-bithienylfluorene polymerizes during milling and its coupling occurs at the e, e ’position.
