Abstract:
The alignment of Cu 2+ ions along a modified DNA helix is studied with either hydroxypyridone (H) or bis(salicylaldehyde)ethylenediamine (S‐en) metalated base pairs (MBPs). The conformational motion of H‐MBP leads to the interlinking of the H‐MBPs by an extended Cu‐O network that is ferromagnetic, whereas the conformational freezing of the S‐en‐MBP leads to an ordered pairwise‐stacked arrangement that is weakly antoferrimagnetic.
