Su, Meng; Tomas-Gamasa, Maria; Serdjukow, Sascha; Mayer, P.; Carell, Thomas (1. November 2013): Synthesis and properties of a Cu(ii) complexing pyrazole ligandoside in DNA. In: Chemical communications, Vol. 50, No. 4: pp. 409-411




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.
