Abstract
A deep hole trap is 7-deazaguanine (Z) - According to time-resolved transient absorption spectroscopy and kinetic modeling - For hole transport in DNA from a guanine (G) to a Z base across one or two intervening adenine-thymine base pairs. The Gibbs energy for hole transport from G to Z was determined to be - 0.19 eV, much larger than values for GG or GGG sites. Thus Z effectively prevents charge migration in DNA.
