Abstract

Exciting DNA threesome: Time-resolved transient absorption spectroscopy has been used to study electron-transfer processes between an excited-state electron acceptor and a ground-state electron donor, separated by a variable number of T:A · T triplet steps in triplex DNA (see figure). The formation and decay of both the acceptor anion radical and donor cation radical can be resolved. Electron tunneling is more effective at longer acceptor-donor distances in triplex than in duplex DNA.
