Eutectogels are an emerging family of soft ionic materials alternative to liquid gels and organogels, offering fresh perspectives for designing functional dynamic platforms in water-free environments. Herein, the first example mixed electronic conducting supramolecular eutectogel composites is reported. A fluorescent glutamic acid-derived low-molecular-weight gelator (LMWG) was found self-assemble into nanofibrillar networks deep eutectic solvents (DES)/poly(3,4-ethylenedioxythiophene) (PEDOT): chondroitin sulfate dispersions. These displayed excellent injectability self-healing properties, high conductivity (up 10-2 S cm-1 ), good biocompatibility, fluorescence imaging ability. This set features turns eutectogels promising adaptive bioimaging electrostimulation applications.

Abstract Ionic conductors have a wide range of development prospects in the field flexible wearable electronics. The polymerizable deep eutectic solvent is more economical, resistant to extreme temperature, and less toxic than traditional hydrogels ionic liquids. In this paper, supramolecular gel prepared by introducing glycol/choline chloride into acrylamide/choline as “hydrogen bond cross‐linking density regulator”. Deep solvents give gels ability resist low (‐25 °C) high (60 temperatures. By 2‐acrylamido‐2‐methyl‐1‐propanesulfonic acid gel, adhesion on copper sheet can reach 90 kPa shows good reusability. Due complex hydrogen interaction it has mechanical properties (strain up 2300%, stress 0.21 MPa). addition, conductivity 0.22 ms cm −1 due presence choline chloride. since polymerization triggered quickly under UV light, allowed us print any shape surface. Such with self‐adhesion, intrinsic conductivity, excellent temperature resistance may applications motion sensors.
