The control of molecular interactions between host and guest is of considerable importance for adsorption and release applications. To address this challenge, polymeric ionic liquid (PIL) brushes were prepared via reversible addition–fragmentation chain transfer polymerization, where we demonstrate that PILs confer a resistance to fouling of the material based on the counterion tunability of PILs. The anion-exchange of poly(1-vinyl-3-buthylimidazolium bromide) was used for the control of the host–guest interactions. Measurement of film thickness, contact angle, and surface morphology of the resulting surfaces were used to confirm the structural characteristics of the cyclodextrin-functionalized PIL brushes. The PIL brushes with switchable properties protect the immobilized host molecule against undesirable interactions without any morphological changes during storage and has potential application in bioseparation and biosensors.

环糊精官能化的聚合物离子液体刷的受控超分子络合

主体与客体之间的分子相互作用的控制对于吸附和释放应用具有相当重要的意义。为了应对这一挑战，通过可逆加成-断裂链转移聚合反应制备了聚合物离子液体（PIL）刷子，在此我们证明了PIL基于PIL的抗衡离子可调谐性赋予了对材料结垢的抵抗力。聚（1-乙烯基-3-溴化咪唑鎓溴化物）的阴离子交换用于控制宿主与客体之间的相互作用。膜厚度，接触角和所得表面的表面形态的测量用于确认环糊精官能化的PIL刷的结构特征。
