Enhanced Stability of Rubrene against Oxidation by Partial and Complete Fluorination
Source abstract
Abstract
We report on the oxidation potential of partially fluorinated (C 42 F 14 H 14, F 14 -RUB) and perfluorinated rubrene (C 42 F 28, 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 (C 42 H 28, RUB).
