Abstract

We have used X-ray photoelectron spectroscopy (XPS) to describe the electronic structure of two newly synthesized derivatives of the 6,13-bis(triisopropylsilylethynyl) pentacene (TIPS-PEN) carrying the 2,2,6,6-tetramethylpiperidin-1-yl)oxidanyl (TEMPO) radical as a substituent. XPS results underline the existing interplay between electronic structure and preparation methods. Our observations suggest a strong influence of the film processing on the shakeup satellite intensities of the N 1s core level spectra. Preparation methods, by tuning the different degree of intermolecular screening, may be use as a tool to influence the properties and the behavior of these materials as thin films, including their local magnetic-exchange coupling.
