An “on‐off‐on” fluorescentsensor was used to sense anionicsurfactant 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 anionicsurfactant SDS, but also its concentration ranges from other species.
