我们报道了一类新型的超分子杂臂星星聚合物通过环糊精主客体化学的形成。可逆加成-断裂链转移聚合从双官能的客体或含炔的链转移剂和铜（I）催化的叠氮化物-炔环加成导致主体和客体含丙烯酰胺聚合物，即聚（N，N-二甲基丙烯酰胺）和聚（N，N-二乙基丙烯酰胺）。随后，形成了一个超分子杂臂星星聚合物，并通过动态光散射和旋转框架核Overhauser效应光谱进行了表征。
We report the formation of a novel class of supramolecular miktoarm star polymers via cyclodextrin host–guest chemistry. Reversible addition–fragmentation chain transfer polymerization from difunctional guest- or alkyne-containing chain transfer agents and copper(I)-catalyzed azide–alkyne cycloaddition leads to host- and guest-containing acrylamido polymers, namely poly(N,N-dimethylacrylamide) and poly(N,N-diethylacrylamide). Subsequently, a supramolecular miktoarm star polymer was formed and characterized via dynamic light scattering and rotating frame nuclear Overhauser effect spectroscopy.
