In this study, we demonstrate the formation of a self-assembled microgel double layer on an electrode surface, utilizing the ability to form electro-responsive, reversible inclusion complexes between microgels modified with ferrocene and β-cyclodextrin in these systems. The bottom layer was based on microgels containing ferrocene moieties and derivatives of cysteine. The presence of the amino acid derivative enabled the formation of the well-packed monolayer on the gold surface through chemisorption, while ferrocene was responsible for electroactivity. The addition of βCD-modified microgel led to the formation of the second monolayer, ultimately creating the double layer. Our investigation focuses on the electrochemically controlled formation and deformation processes of the double microgel layer.
在本研究中，我们展示了在电极表面形成自组装微凝胶双层的过程，利用了在这些体系中用二茂铁和β-环糊精修饰的微凝胶之间形成电响应性、可逆包合物的能力。底层基于含有二茂铁部分和半胱氨酸衍生物的微凝胶。氨基酸衍生物的存在使得通过化学吸附在金表面形成排列紧密的单层，而二茂铁则负责电活性。添加β-环糊精修饰的微凝胶导致形成第二个单层，最终形成双层。我们的研究重点是双微凝胶层的电化学控制形成和变形过程。
