Abstract

Hydroxyphenylbenzazole compounds that are useful for the selective detection of zinc, aluminum, chromium, and iron cations in vitro and in vivo. The Hydroxyphenylbenzazole compounds include a 2-hydroxyphenyl group bound to a single benzazole group; a first ligand group that is a Schiff base moiety; and a second ligand group selected from a Schiff base moiety and a hydroxyl group.
