Probing Charge Transfer in Benzodifuran–C₆₀ Dumbbell‐Type Electron Donor–Acceptor Conjugates: Ground‐ and Excited‐State Assays

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...
