Abstract

It has been previously found that water-soluble copper porphyrin Cu(TMpy-P4) is able to create a photoinduced exciplex in interaction with DNA [1]. However, one rather puzzling aspect of this process lies in the fact that major part of CuP molecules is known to intercalate between GC base pairs when mixed with DNA while exciplex can be formed only at AT site of double helix. This aspect was noted in [2] where the mechanism of fast porphyrin translocation from GC to AT site has been proposed and discussed.
