Metal Templated Receptors for the Effective Complexation of Dicarboxylates

Article abstract of DOI:10.1016/0040-4039(95)00337-C

In this paper we show that a thiourea-functionalized terpyridine unit can be induced to form, in the presence of ruthenium(II), a well-ordered recognition site for dicarboxylate ions.Strong binding to the self-assembled receptor can be followed by 1H NMR in DMSO and association constants of >10⁴ M^-1 were measured in certain cases.
