我们报告的氧化电位的部分氟化（C42 F14 H14，F-14-RUB）和全氟化红荧烯（C42 F28，PF-RUB）研究的循环伏安法（CV）在溶液中，以及通过椭圆偏振光谱和近边X射线吸收精细结构（NEXAFS）光谱结合密度泛函理论计算的薄膜。由于它们不同的电子结构，氟化衍生物具有更高的氧化电位，比红荧烯（C42 H28，RUB）更稳定。
We report on the oxidation potential of partially fluorinated (C42F14H14, F-14-RUB) and perfluorinated rubrene (C42F28, PF-RUB) studied by cyclic voltammetry (CV) in solution as well as by spectroscopic ellipsometry and near edge X-ray absorption fine structure (NEXAFS) spectroscopy in thin films in combination with density functional theory computations. Due to their different electronic structure, the fluorinated derivatives have a higher oxidation potential and are more stable than rubrene (C42H28, RUB).
