The synthesis of a novel conjugated polymer containing fused pyridinium units in its main chain is reported. A precursor polymer possessing pyridine and tetrafluorophenylene moieties was reacted in the presence of Lewis acid additives to promote the intramolecular nucleophilic aromatic substitution (S N Ar) reaction. The polymer reaction with BE 3 -OEt 2 gave a product polymer soluble in polar organic solvents, and the successful formation of fused pyridinium ring structures was spectroscopically confirmed. The electrochemical and optical properties of the synthesized polymers were also investigated, suggesting that the polymer product has a narrower band gap than the precursor polymer.

通过后聚合分子内环化反应合成具有稠环吡啶单元的共轭聚合物

报道了一种在主链中含有稠合吡啶鎓单元的新型共轭聚合物的合成。具有吡啶和四氟亚苯基部分的前体聚合物在路易斯酸添加剂的存在下反应，以促进分子内亲核芳族取代 (SN Ar) 反应。与 BE 3 -OEt 2 的聚合物反应产生了可溶于极性有机溶剂的聚合物产物，并且通过光谱证实了稠合吡啶环结构的成功形成。还研究了合成聚合物的电化学和光学性质，表明聚合物产物的带隙比前体聚合物更窄。报道了一种在主链中含有稠合吡啶鎓单元的新型共轭聚合物的合成。具有吡啶和四氟亚苯基部分的前体聚合物在路易斯酸添加剂的存在下反应，以促进分子内亲核芳族取代 (SN Ar) 反应。与 BE 3 -OEt 2 的聚合物反应产生了可溶于极性有机溶剂的聚合物产物，并且通过光谱证实了稠合吡啶环结构的成功形成。还研究了合成聚合物的电化学和光学性质。
