In this work, we found a new class of controlled/″living″ polymerization system, which proceeds bidirectional fashion using click reaction of AB monomer bearing azide and alkyne functionalities in a single molecule. The click polymerization of the AB monomer proceeded well using both azide and alkyne initiators in a well-controlled manner in either growth direction to afford polymers with predetermined molecular weights and narrow molecular weight distributions, as well as the terminal structures inherited from the initiator. Especially, the polymerizations with the difunctional initiators provided well-defined linear polymers with azide or alkyne groups at both termini. This approach also allows for polymerization control over the second monomer to give a block copolymer.
在本研究中，我们发现了一类新型的可控/“活性”聚合体系，该体系利用单分子中带有叠氮基和炔基官能团的AB单体的点击反应以双向方式进行。使用叠氮化物和炔化物引发剂，AB单体的点击聚合在任一生长方向上均能以良好控制的方式顺利进行，从而得到具有预定分子量和窄分子量分布的聚合物，以及继承自引发剂的末端结构。特别地，使用双官能引发剂进行的聚合反应可得到两端带有叠氮基或炔基的结构明确的线性聚合物。这种方法还能够对第二种单体的聚合进行控制，从而得到嵌段共聚物。
