    Research Progress on Living Polymerization of Allenes Catalyzed by Nickel Complexes

    • 摘要: 联烯因具有1,2-累积双键的独特结构,可表现出特殊的反应活性,在适当的条件下能选择性地进行1,2-或2,3-位聚合。末端连有不同取代基的联烯,聚合后连于主链的双键可进一步与其他功能基团反应,从而获得新的功能性材料。本文主要介绍了烯丙基镍配合物及聚3-己基噻吩(P3HT)两种催化体系聚合联烯的方法,并讨论了镍配合物聚合联烯时单体上的取代基、反应溶剂对聚合的影响,不同镍配合物催化剂在催化联烯活性聚合方面的应用及聚噻吩体系聚合联烯获得的聚合物的各种组装性能,以及使用烯丙基镍催化体系聚合手性联烯单体获得具有稳定结构的光学活性聚联烯等内容。

       

      Abstract: Allene derivatives have cumulated double bonds and can be regarded as the isomers of propargyl derivatives. Due to their unique structures with 1,2-cumulative double bonds, they can exhibit special reactivity and can selectively conduct 1,2- or 2,3-position polymerization under appropriate conditions. Taking advantage of this characteristic, polymers with exomethylene substituents can be obtained through the selective polymerization of either part (1,2- or 2,3-)of the cumulated double bonds. Allylnickel( II)complexes and poly( 3-hexylthiophene)( P3HT)have been reported to promote the living/controlled polymerization of allene derivatives. The polymerization of allene using the catalysts such as allylnickel( II)complexes and poly( 3-hexylthiophene)( P3HT)is presented with detailed discussion, including the impact of the substituents on the monomers, the reaction solvent during the polymerization using allylnickel( II)complexes as catalyst, the application of living polymerization of allene using different allylnickel( II)complexes, and the self-assembly performance of polyallenes using P3HT as catalyst. In addition, living polymerizations of chiral allene monomers with allylnickel complex as a catalyst afforded helical polyallenes was also described. The helical structure of the polyallenes was quite stable with a preferred handedness in aprotic solvents. The helical polyalkenes behaved pH-responsive property due to the amino group on the pendant.
