Abstract
The photophysical behaviour of a pyrene-modified adenine base is examined. Time-dependent absorption and fluorescence spectroscopy is used to shed light on the fluorescence behavior and the charge transfer between the fluorophore and the nucleobase. The results from TCSPC, fluorescence upconversion and pump-probe absorption spectroscopy are reported, compared and analyzed. This study is a prerequisite for the detailed characterization of RNA dynamics in real time and on a molecular time scale.
