我们展示了一种基于聚合物反应的带有高极性基团的功能性二取代聚乙炔的简单合成路线。设计了一种含五氟苯基酯基的二苯乙炔，并进行了聚合反应，得到了PFP活化的酯功能化二取代聚乙炔（P1）。以P1为母体聚合物，分别与不同的胺反应，在温和条件下高产率地合成了一系列带有手性基团、羟基和羧基的功能性双取代聚乙炔。光谱表征数据表明，聚合物的结构与预期结果一致。研究了聚合物的螺旋度和发光性能。
We demonstrate a facile synthetic route to functional disubstituted polyacetylenes bearing highly polar groups based on polymer reactions. A pentafluorophenyl (PFP) ester-containing diphenylacetylene was designed and polymerized to obtain PFP activated ester-functionalized disubstituted polyacetylene (P1). P1 was used as a parent polymer to further react separately with diverse amines, giving rise to a series of functional disubstituted polyacetylenes with a chiral moiety and hydroxyl and carboxyl groups in high yields under mild condition. Spectral characterization data indicated that the polymers' structures were well consistent with the expected results. The helicity and emission property of polymers were also studied.
