Plastic 1–14 pH indicator strips were prepared via cross-linking of an ionic liquid (IL) monomer, 1-butyl-3-vinylimidazolium bromide ([Bvim][Br]), with acrylonitrile, and followed by anion-exchange with anionic dyes. The resultant pH indicator strips exhibit enhanced pH-responsive colour changes and robust pH-response reversibility in both aqueous and organic solutions.
