Electroactive supramolecular gels with multistimuli responsiveness were fabricated through host-guest interactions between a host polymer containing β-cyclodextrin (CD) and an ionic liquid (IL) type asymmetric gemini guest, which contains both ferrocene (Fc) and bis(trifluoromethyl-sulfonyl)imide (TFSI) as the respective α- and ω-guest groups. Owing to the multiple stimuli-responsiveness of the host-guest interactions, reversible sol-gel 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-gel transition behavior could be electrochemically controlled by the applied voltage, without using additional supporting electrolyte.
通过含β-环糊精（CD）的主体聚合物与离子液体（IL）型不对称双子客体之间的主客体相互作用，制备了具有多刺激响应性的电活性超分子凝胶，该双子客体同时含有二茂铁（Fc）和双（三氟甲基磺酰）亚胺（TFSI）作为各自的α-和ω-客体基团。由于主客体相互作用的多重刺激响应性，可逆的溶胶-凝胶相变可由包括温度、电化学/化学氧化还原和阴离子交换反应在内的各种刺激触发。由于IL双子客体的固有导电特性，溶胶-凝胶转变行为可通过施加电压进行电化学控制，而无需使用额外的支持电解质。
