Addressing the properties of "Metallo-DNA" with a Ag(i)-mediated supramolecular duplex

The silver-nucleoside complex [Ag(i)-( 3-cytidine) ], , self-assembles to form a supramolecular metal-mediated base-pair array highly analogous to those seen in metallo-DNA. A combination of complementary hydrogen-bonding, hydrophobic and argentophilic interactions drive the formation of a double-he...

Description
Summary:The silver-nucleoside complex [Ag(i)-( 3-cytidine) ], , self-assembles to form a supramolecular metal-mediated base-pair array highly analogous to those seen in metallo-DNA. A combination of complementary hydrogen-bonding, hydrophobic and argentophilic interactions drive the formation of a double-helix with a continuous silver core. Electrical measurements on show that despite having Ag···Ag distances within
