Highly electron deficient benzo[ghi]perylenetriimide (BPTI) chromophores were persistently anchored to a metal oxide electrode surface and reversible formation of their radical anions was shown in air‐saturated aqueous buffer solution. Our results show a very low reaction‐rate constant of BPTI .− with O 2 ( k =1.92±0.05×10 −2 s −1 ). BPTI is a robust chromophore that can be used as the electron acceptor in molecule‐based artificial photosynthetic devices for direct water splitting in aqueous phase.
