Supramolecular eutectogels, an emerging class of materials that have just developed very recently, offer a new opportunity for generating functional supramolecular gel materials in biocompatible anhydrous or low-water media. As the first example of supramolecular G4 eutectogels, complexes of natural guanosine and H BO exhibited excellent gelation capacity in choline chloride/alcohol deep eutectic solvents. The as-prepared supramolecular eutectogels displayed unexpected solvent-induced chiral inversion and significantly high ionic conductivity (up to 7.78 mS cm ), as well as outstanding thixotropic/injectable properties, high thermal stability and excellent electrochromic activity. These features make these versatile supramolecular G4 eutectogels promising candidates for developing next-generation flexible electronics with low environmental impact.
超分子共晶胶，这是一个新兴的材料领域，最近才得到了快速发展，为在生物相容性的无水或低水介质中生成功能性超分子凝胶材料提供了新的机会。作为超分子 G4 共晶胶的第一个例子，天然鸟嘌呤和 H BO 的配合物在氯化胆碱/醇深共晶溶剂中表现出优异的凝胶化能力。所制备的超分子共晶胶表现出意想不到的溶剂诱导手性反转和非常高的离子电导率（高达 7.78 mS cm ），以及出色的触变性/可注射性、高热稳定性和优异的电致变色活性。这些特性使得这些多功能的超分子 G4 共晶胶成为开发具有低环境影响的下一代柔性电子器件的有前途的候选材料。
