title: Direct observation of electron-transfer-induced conformational transformation (molecular actuation) in a bichromophoric electron donor.
abstract: With the aid of laser-flash photolysis, the one-electron oxidation of conformationally mobile tetramethoxydibenzobicyclo[4.4.1]undecane (1), using photoexcited chloranil as an oxidant, allows us to show that extended 1(+•) undergoes a conformational transformation to π-stacked folded 1(+•) on a microsecond time scale (τ ≈ 1 μs), which is at least six times longer than that found for the conformationally locked model compound.
