title: Efficient interstrand excess electron transfer in PNA:DNA hybrids.
abstract: PNA:DNA strands were prepared containing a flavin electron donor and a thymine dimer acceptor, which gives a strand break upon single electron reduction. With these constructs, it was confirmed that an excess electron transfer through the base stack can be efficient in an interstrand fashion. The effect of an increased distance, a changed sequence, and stacking was explored.
