A backwards strategy for achieving Mn 2+ /Ca 2+ selectivity was demonstrated: Instead of optimizing binding of Mn 2+ , the bapta ligand (upper structure in scheme) was modified by changing O to N donors to discourage association by unwanted competitor Ca 2+ . Attachment of a fluorophore gave a Mn 2+ ‐selective on‐fluorescent probe for use in live cell imaging.
