Discrimination between hard metals with soft ligand donor atoms: An on-fluorescence probe for manganese(II)

Jian Liang, James W. Canary

Research output: Contribution to journalArticle


A backwards strategy for achieving Mn2+/Ca2+ selectivity was demonstrated: Instead of optimizing binding of Mn2+, the bapta ligand (upper structure in scheme) was modified by changing O to N donors to discourage association by unwanted competitor Ca2+. Attachment of a fluorophore gave a Mn2+- selective on-fluorescent probe for use in live cell imaging.
