- Abstract
Visible light‐induced charge separation and directional charge transfer are cornerstones for artificial photosynthesis and the generation of solar fuels. Here, we report synthetic access to a series of noble metal‐free donor‐acceptor dyads based on bodipy light‐absorbers and redox‐active quinone/anthraquinone charge storage sites. Peripheral functionalization of the quinone/anthraquinone units with alkynes primes the dyads for integration into a range of light‐harvesting systems, e. g., by Cu‐catalyzed cycloadditions (CLICK chemistry) or Pd‐catalyzed C−C cross‐coupling reactions. Initial photophysical, electrochemical and theoretical analyses reveal the principal processes during the light‐induced charge separation in the reported dyads.
