## Abstract Receptor **1** was designed to bind barbiturate substrates through a six‐point hydrogen‐bonding motif only in the absence of metal allosteric cofactors. It was predicted that the binding of metal ions by bipyridine ligands in **1** would result in a geometric change in the receptor to i
