Enormous effort has been put to the detection and recognition of various heavy metal ions due to their involvement in serious environmental pollution and many major diseases. The present work has developed a single fluorescent sensor ensemble that can distinguish and identify a variety of heavy metal ions. A pyrene-based fluorophore (PB) containing a metal ion receptor group was specially designed and synthesized. Anionic surfactant sodium dodecyl sulfate (SDS) assemblies can effectively adjust its fluorescence behavior. The selected binary ensemble based on PB/SDS assemblies can exhibit multiple emission bands and provide wavelength-based cross-reactive responses to a series of metal ions to realize pattern recognition ability. The combination of surfactant assembly modulation and the receptor for metal ions empowers the present sensor ensemble with strong discrimination power, which could well differentiate 13 metal ions, including Cu²⁺, Co²⁺, Ni²⁺, Cr³⁺, Hg²⁺, Fe³⁺, Zn²⁺, Cd²⁺, Al³⁺, Pb²⁺, Ca²⁺, Mg²⁺, and Ba²⁺. Moreover, this single sensing ensemble could be further applied for identifying different brands of drinking water.
