摘要
Excess electron transfer dynamics in DNA hairpins was investigated by femtosecond laser flash photolysis of a donor-DNA-acceptor system using N,N-dimethylaminopyrene and diphenylacetylene as an electron donor and acceptor, respectively. It was revealed that the excess electron hopping rate between T's is faster than that of the hole.
