An “on‐off‐on” fluorescent sensor was used to sense anionic surfactant SDS with high sensitivity and selectivity due to the formation of 1:1 complex with SDS. The detection range can be adjusted by altering the substituting alkyl chain length (NHR in the figure). The sensor array can discriminate not only anionic surfactant SDS, but also its concentration ranges from other species.
