The one-electron oxidation of tetramethoxydibenzobicyclo[4.4.1]undecane (4) prompts it to undergo a clam-like electromechanical actuation into a cofacially pi-stacked conformer as established by (i) electrochemical analysis, (ii) by the observation of the intense charge-resonance transition in the near IR region in its cation radical spectrum, and (iii) by X-ray crystallographic characterization of the isolated cation radical salt (4(+*) SbCl(6)(-)).
四甲氧基二苯并双环[4.4.1]十一烷(4)的单电子氧化促使其发生类似蛤的机电驱动,形成一个共面π堆积构象体,这是通过以下方式确定的:(i)电化学分析,(ii)观察其阳离子自由基光谱中近红外区域强烈的电荷共振跃迁,以及(iii)对分离出的阳离子自由基盐(4(+*)SbCl(6)(-))进行X射线晶体学表征。
