Good color sense : A sensing material ( S1 ) containing imidazolium‐anchored binding groups is used with a suitable dye (methylene blue) in a simple two‐step protocol for the colorimetric detection of anionic surfactants in water (see picture). A detection limit of 1 ppm can be achieved, and the method is free from the use of hazardous solvents.
