Abstract

Invited for this month's cover picture is the group of Evgeny A. Kataev at the Technical University Chemnitz. The cover picture shows the authors' association of fluorescence anion sensing with pearl hunting - the activity of recovering pearls from wild molluscs. In the presented work, the group of Kataev has developed a new water-soluble amido-amine azacryptand bearing a fluorescence anthracene dicarboxamide fragment. With the help of the fluorescent receptors (a hand) one can catch the phosphate anion (a glowing pearl) and visualize this binding event. The recognition of phosphate and oxalate has led to a fluorescent enhancement in a selective manner. Read the full text of their Communication at https://doi.org/10.1002/open.201900309.
