Synthesis of brush polymers via Bergman cyclization

Keywords： Bergman cyclization , enedyine , polymerization , brush polymers

以含有烯二炔结构的枝状化合物单体在真空、282℃条件下,通过Bergman环化反应,热聚合为具有刚性的共轭主干、带有枝状化合物侧链的刷状高分子聚合物。核磁共振光谱、广角光散射、凝胶色谱、红外光谱、紫外-可见光谱等表征结果,证明所合成的两种聚合产物确实是具有共轭结构的刷状高分子。

Two brush polymers were synthesized utilizing two frechet enedyine-containing dendronized polymers via Bergman cyclization at 282℃ under vacuum,respectively.The brush polymer were characterized with a variety of brush techniques,including IR,UV-Vis,GPC,NMR spectroscopy and wide-angle laser light scattering technology.The results indicated that the brush polymers with conjugated structure were obtained.
