摘要：

(Figure Presented) Either way: An IrIII complex strongly coupled to a DNA base stack can inject a hole or an electron in DNA upon irradiation (see picture). With strands containing the modified bases CPA and CPC/BrU, which serve as oxidative and reductive probes, respectively, photolysis of Ir-DNA conjugates leads to a "ping-pong" electron transfer, with both hole and electron migration. © 2008 Wiley-VCH Verlag GmbH & Co.
