We report a new method to fabricate highly stretchable and highly conductive fluorescent ionogels via self-catalytic crosslinking of poly(ionic liquid (IL))-based copolymers containing epoxy groups in ILs without adding any conventional crosslinkers and chromophores. Here, the ILs serve as a solvent, electrolyte, and catalyst, while the product of the ring-opening reactions acts as crosslinking junctions. The results reveal that these systems are typical autocatalytic systems and that the IL anion type significantly influences the curing reaction kinetics. These ionogels exhibit excellent stretchability (>1200%), high ionic conductivity (>1 mS cm-1), and good temperature tolerance (-40 to 200°C). Surprisingly, the special crosslinking structures make the ionogels show typical aggregation-induced emission behavior and possess tunable photoluminescence properties. Moreover, ionogel-based strain sensors exhibit fast response speed, excellent temperature tolerance and stability, and can monitor various human motions. Therefore, our study provides a facile method to utilize several distinct properties of ILs and PILs for designing multifunctional ionogels that serve as flexible conductive and fluorescent materials. In the experiment, the researchers used many compounds, for example, 1-Butyl-3-vinyl-1H-imidazol-3-ium hexafluorophosphate(V) (cas: 915358-85-9Reference of 915358-85-9).
1-Butyl-3-vinyl-1H-imidazol-3-ium hexafluorophosphate(V) (cas: 915358-85-9) belongs to imidazole derivatives. The solubility of imidazoles in ethers is lower than that in alcohols and decreases with increasing chain length of the ethers . In contrast, the solubility of benzimidazoles in alcohols (C3–C6) is higher than in water and generally decreases with a Imidazole also acts as a microtubule destabilizing agents and inhibits topoisomerase and Cytochrome P450 Family 26 Subfamily A Member 1 (CYP26A1) enzymes.Reference of 915358-85-9
