Influence of the heteroatom on the properties and
transistor performance of soluble thiophene-,
selenophene- and tellurophene-vinylene copolymers

Figure S1. Photo Electron Spectroscopy in Air (PESA) spectra of a thin film of P3TV. The
ionization potential was calculated by extrapolating a fit of the square root of the photoelectron
emission yield as a function of excitation photon energy.
