Abstract
Abstract 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 3 BO 3 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 −1 ), 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.
