Book synopsis

This dissertation introduces a new field of DNA §photonics centering on the electronic properties of §DNA, which emerges after the initial controversies §regarding the long-range conductivity and wire-type §behavior of DNA have been widely settled. DNA §photonics study is not solely focused on charge §transfer phenomena but encompasses all possible §photophysical processes and their potentially §complex interplays. For instance, ultrafast §electronic energy migration, dissipation, and (de)§localization on the femtosecond time scale are shown §to be crucial for the description of light-induced §dynamics in DNA and have been thoroughly §investigated in this dissertation. In addition to §measurements on natural single and double-stranded §DNA, this dissertation also presents experimental §data on a series of functionalized DNA systems §obtained by state-of-the-art femtosecond §broadband pump probe spectroscopy. The results §illustrate the distance dependence of charge §transfer, emphasize the role of the initial §electronic excitation on energy transfer dynamics, §and highlight the influence of structural factors on §both processes in DNA.
