在此，我们报道了利用四氮北风烯逆电子需求的Alder偶联应用于聚合物端功能化和聚合物偶联。通过SEC， DOSY NMR和LCxSEC分析，发现该反应适用于聚合物-聚合物偶联，只需在环境条件下将各组成均聚物混合在一起，不使用催化剂，添加剂或外部刺激，即可得到双嵌段共聚物。
Herein we report the use of a tetrazinenorbornene inverse electron demand Diets Alder conjugation applied to polymer end-functionalization and polymer polymer coupling. The reaction was found to be applicable to polymer polymer coupling, as judged by SEC, DOSY NMR, and LCxSEC analyses, giving diblock copolymers by merely mixing the constituent homopolymers together under ambient conditions, using no catalyst, additive, or external stimulus.
