The filled and empty electronic states were measured by means of UV photoemission and inverse photoemission spectroscopy on a single monolayer and a 20 monolayer thick film. The ionization energy and the electron affinity of the organic film were deduced

A comparison between filled and empty states can help to reveal the creation and the value of an interface dipole, which shifts the sample vacuum energy level with

However, if the interfacial dipoles of the PVDF–TrFE film are poled “up” instead, the characteristic inverse photoemission (IPES) signature of the SCO complex in the HS form persists down to 100 K

• temperatures, the spin state is determined by the polarization of the ferroelectric substrate. If the substrate is poled “up”, the SCO molecules will remain HS; conversely, the SCO molecules will adopt the LS form for a substrate poled “down”. b) Inverse photoemission spectrum at 170 K for a 25 molecule thick
