Abstract
- The redox properties of metallo-base pairs remain to be elucidated. Herein, we report the detailed <superscript>1</superscript>H/<superscript>13</superscript>C/<superscript>109</superscript>Ag NMR spectroscopic and cyclic voltammetric characterisation of the [Ag(cytidine)<subscript>2</subscript>]<superscript>+</superscript> complex as isolated cytosine–Ag<superscript>+</superscript>–cytosine (C–Ag<superscript>+</superscript>–C) base pairs. We also performed comparative studies between cytidine/Ag<superscript>+</superscript> and other nucleoside/Ag<superscript>+</superscript> systems by using cyclic voltammetry measurements. In addition, to evaluate the effect of [Ag(cytidine)<subscript>2</subscript>]<superscript>+</superscript> formation on the chemical reduction of Ag<superscript>+</superscript> to Ag, we utilised the redox reaction between Ag<superscript>+</superscript> and tetrathiafulvalene (TTF). We found that Ag<superscript>+</superscript>-mediated base pairing lowers the redox potential of the Ag<superscript>+</superscript>/Ag couple. In addition, C–Ag<superscript>+</superscript>–C base pairing makes it more difficult to reduce captured Ag<superscript>+</superscript> ions than in other nucleoside/Ag<superscript>+</superscript> systems. Remarkably, the cytidine/Ag<superscript>+</superscript> system can be utilised to control the redox potential of the Ag<superscript>+</superscript>/Ag couple in DMSO. This feature of the cytidine/Ag<superscript>+</superscript> system may be exploited for Ag nanoparticle synthesis by using the redox reaction between Ag<superscript>+</superscript> and TTF.
