Synthesis and properties of a Cu(ii) complexing pyrazole ligandoside in DNA†
Abstract
The development of metal base pairs is of immense importance for the construction of DNA nanostructures. Here we report the synthesis of a biaryl pyrazole–phenol nucleoside that forms in DNA a stable self-pair upon complexation of a Cu(II) ion. A sequence with five consecutive pyrazole nucleotides allows the complexation of five Cu(II) ions in a row.
