Combination of a Fluorescent Dye and a Zn−S Cluster and Its Biological Application as a Stain for Bacteria

Abstract

An ionic-pair charge-transfer salt [C15H16N3]+[Zn8S(SC6H5)15·H2O]− (1) featuring a fluorescent dye and a wurtzite-like octanuclear Zn−S cluster shows high stability when staining bacteria Escherichia coli, Salmonella typhimurium, and Clostridium novyi NT
