Rigid electron donor–acceptor conjugates ( 1 – 3 ) that combine π‐extended benzodifurans as electron donors and C 60 molecules as electron acceptors with different linkers have been synthesized and investigated with respect to intramolecular charge‐transfer events. Electrochemistry, fluorescence, and transient absorption measurements revealed tunable and structure‐dependent charge‐transfer processes in the ground and excited states. Our experimental findings are underpinned by density‐functional theory calculations.
