Quantum yields of up to 14 % for the formation of a long‐lived, charge‐separated state can be achieved in flavin‐capped DNA hairpins. The excited flavin state is quenched by electron‐transfer processes from adjacent DNA bases. The introduction of multiple (dG:dC) base pairs leads to efficient hole trapping that competes with the charge recombination through dA‐hopping processes.
