提出了一种利用分子内氢键作用控制蒽醌类π分子体系吸电子能力的新策略。由于在AQ衍生物中引入了大体积的芳基磺酰胺基团，形成了有效的分子内N-H-O氢键相互作用和稳定了阴离子自由基的状态，从而增强了AQ的电子接受性能。
A new strategy for controlling the electron-accepting ability of an anthraquinone (AQ)-based π-molecular system is proposed to take advantage of intramolecular hydrogen bonding interactions. The electron-accepting properties of AQ are enhanced by the introduction of bulky arylsulfonamide groups into AQ derivatives due to the formation of effective intramolecular N–H⋯O hydrogen bonding interaction and stabilization of the anion radical state even in solution.
