]. Taking into account a broadening upon transition from single molecules in solution to the solid state as well as energy shifts due to different polarizationscreening, there is very good agreement between our data and those in solution from the literature. This nicely corroborates the interpretation of

In order to develop and improve the performance of organic-based electronic devices an
, the underlying reasons for energetic shifts in photoemission are complex. It is important to distinguish between a variation of the local charge at the considered atom and a different ability for a polarizationscreening of the environment. Combined X-ray photoemission spectroscopy (XPS) and X-ray
state [5][19]. On the other hand, in case of fluorinated Pcs the absence of a local charge transfer process at the fluorine atom allows the estimation of the polarizationscreening via the corresponding Auger parameter [19].
