Metal templated receptors for the effective complexation of dicarboxylates

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 >10...

Description
Summary: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 >10 4 M −1 were measured in certain cases. A thiourea functionalized terpyridine ligand that assembles in the presence of Ru(II) ions to form a receptor for dicarboxylates is described.
