Hole transfer in DNA: DNA as a scaffold for hole transfer between two organic molecules

Hole transfer process in ODNs conjugated with two organic molecules, pyrene (Py) and phenothiazine (Ptz) was investigated with the pulse radiolysis measurements. Monitoring the transient absorption of Py+ and Ptz+, it was shown that the hole transfer rate was dependent on the distance and sequence between Py and Ptz.
