Molecular actuator: Redox-controlled clam-like motion in a bichromophoric electron donor

Chebny, Vincent J.,Shukla, Ruchi,Lindeman, Sergey V.,Rathore, Rajendra

, p. 1939 - 1942 (2009)

The one-electron oxidation of tetramethoxydibenzobicyclo[4.4.1]undecane (4) prompts it to undergo a clam-like electromechanical actuation into a cofacially -stacked conformer as established by (i) electrochemical analysis, (ii) by the observation of the i
