文摘

Electroactive supramolecular gels with multistimuli responsiveness were fabricated through host鈥揼uest interactions between a host polymer containing 尾-cyclodextrin (CD) and an ionic liquid (IL) type asymmetric gemini guest, which contains both ferrocene (Fc) and bis(trifluoromethyl-sulfonyl)imide (TFSI^{鈥?/sup>) as the respective 伪- and 蠅-guest groups. Owing to the multiple stimuli-responsiveness of the host鈥揼uest interactions, reversible sol鈥揼el phase transition could be triggered by various stimuli, including temperature, electrochemical/chemical redox and anion-exchange reactions. Due to the intrinsically conductive properties of the IL gemini guest, the sol鈥揼el transition behavior could be electrochemically controlled by the applied voltage, without using additional supporting electrolyte.}
