Charge transport anthraquinones

The anthraquinone derivatives may oxidize DNA when they are randomly bound to the DNA or attached to it covalently at particular locations. Radical cations introduced in the DNA by the excited anthraquinone cause damage both within the binding pocket and locally separated from the anthraquinone binding site. A mechanism has been proposed for long-range charge transport in DNA which depends on the spontaneous distortion of the DNA structure and which is called phonon-assisted polaron hopping [243-245].
