Hydrogen-bond recognition of nucleosides by oligopyridine ligands and their ruthenium complexes
Abstract
The compound L1 was formed by the covalent attachment of a thymine residue to a 2,2′:6′,2″-terpyridine metal-binding domain; L1 and its ruthenium(II) complexes show specific hydrogen-bonding interactions with 2′,3′-isopropylideneadenosine L4 in chloroform or acetonitrile solution {log K[RuL1(tpy)]2+ : L4≈1.44 at 298 K, MeCN}.
