title: Dynamics of electron injection in DNA hairpins.
abstract: The dynamics of electron injection has been investigated in DNA hairpins possessing a stilbenediether electron donor linker by means of femtosecond transient absorption spectroscopy. Ultrafast electron injection and charge recombination are observed with neighboring cytosine or thymine bases; however, guanine-guanine base pairs are not reduced, permitting the investigation of the distance dependence of charge injection.
