Su, Meng; Tomas-Gamasa, Maria; Carell, Thomas (2015): DNA based multi-copper ions assembly using combined pyrazole and salen ligandosides. In: Chemical Science, Vol. 6, No. 1: pp. 632-638




The DNA structure is an ideal building block for the construction of functional nano-objects. In this direction, metal coordinating base pairs (ligandosides) are an appealing tool for the future specific functionalization of such nano-objects. We present here a study, in which we combine the metal ion coordinating pyrazole ligandoside with the interstrand crosslinking salen ligandoside system. We show that both ligandosides, when combined, are able to create stable multi-copper ion complexing DNA double helix structures in a cooperative fashion.
