Multimodal Cyclotriguaiacylene-Fluorescein Supramolecular Sensor for Field-Deployable Monitoring of Strontium in Complex Environmental Waters.
Selective quantification of dissolved Sr2+ in chemically complex environmental waters remains a significant analytical challenge because of the closely related physicochemical properties of alkaline-earth ions and the matrix complexity of natural waters. Herein, a fluorescein-functionalized cyclotriguaiacylene macrocyc...
