摘要

We synthesized 6-arm star-shaped polystyrene-ran-poly(methyl methacrylate) copolymers ((S-r-M)(6)) for mechanically robust and thermally stable ion gels containing an ionic liquid of 1-ethyl-3-methylimidazolium bis(trifluoromethyl sulfonyl)imide ([EMI]TESI]). The (S-r-M)(6)-based gels exhibited higher elastic modulus (E similar to 1.67 x 10(5) Pa), which is more than five-times that (similar to 0.29 x 10(5) Pa) of linear PS-r-PMMA-based ion gels at the same Sty content (similar to 29 mol%), irrespective of applied mechanical strains (stretching and compression). In addition, they showed outstanding thermal stability. For example, the gel-sol transition temperature (T-gel) of (S-r-M)(6) gels was similar to 72 degrees C, compared with that (similar to 56 degrees C) of linear PSr-PMMA-based ion gels. These physical properties of gels were further improved by increasing total molecular weight and the fraction of styrene, giving E of similar to 3.8 x 10(5) Pa and T-gel of similar to 163 degrees C. The resulting gels were functionalized by introducing electrochemiluminescence luminophores (tris(2,2'-bipyridyl) ruthenium(II) hexafluorophosphate). By utilizing the mechanical robustness of the (S-r-M)(6) gels, we fabricated emissive electrochemical displays through 'cut-and-stick' process. Moreover, the thermally stable (S-r-M)(6) gels indicated good dimensional stability, offering a chance to demonstrate ECL devices that operate even at high temperatures.
