AbstractThe investigation on charge migration mechanism in double helix DNA is an important current issue extensively studied in the overlapping field of chemistry and biology. We have designed and synthesized a series of supermolecular assemblies of double helix DNA to study charge migration mechanism in DNA by measuring Ap fluorescence and its relative fluorescence quantum yield. Experimentaly, we have distinguished and observed superexchange mechanism of charge transfer in the supermolecular assemblies of double helix DNA, which plays a role in DNA for short distance; but hopping mechanism may be exhibited by the phonon-assisted polaron-like hopping migration.
