Eutectogels are an emerging family of soft ionic materials alternative to ionic liquid gels and organogels, offering fresh perspectives for designing functional dynamic platforms in water-free environments. Herein, the first example of mixed ionic and electronic conducting supramolecular eutectogel composites is reported. A fluorescent glutamic acid-derived low-molecular-weight gelator (LMWG) was found to self-assemble into nanofibrillar networks in deep eutectic solvents (DES)/poly(3,4-ethylenedioxythiophene) (PEDOT): chondroitin sulfate dispersions. These dynamic materials displayed excellent injectability and self-healing properties, high ionic conductivity (up to 10 S cm ), good biocompatibility, and fluorescence imaging ability. This set of features turns the mixed conducting supramolecular eutectogels into promising adaptive materials for bioimaging and electrostimulation applications.
低共熔凝胶是一类新兴的软离子材料，可作为离子液体凝胶和有机凝胶的替代品，为无水环境中功能性动态平台的设计提供了新的视角。本文首次报道了混合离子和电子导电的超分子低共熔凝胶复合材料。研究发现，一种荧光谷氨酸衍生的低分子质量凝胶剂（LMWG）在深共晶溶剂（DES）/聚（3,4-亚乙基二氧噻吩）（PEDOT）：硫酸软骨素分散体中自组装成纳米纤维网络。这些动态材料表现出优异的可注射性和自修复性能、高离子电导率（高达 10 S cm ）、良好的生物相容性和荧光成像能力。这一系列特性使混合导电超分子低共熔凝胶成为生物成像和电刺激应用中很有前途的自适应材料。
