The electronic band structure of a tetrakis(thiadiazole)porhyrazine (H2TTDPz) thin film prepared on SiO2, which is a system close to a real device one, was studied by photoelectron spectroscopy (PES). Although the film was grown on a bumpy surface, clear electronic band dispersion was observed along the surface-normal direction. The bandwidth of the highest occupied molecular orbital (HOMO) band was approximately 180 meV. By analyzing the PES result using the tight-binding method, the transfer integral for the π−π interaction, the effective mass of the HOMO hole, and the hole mobility were estimated to be approximately 45±10 meV, 1/m∗h=(0.14±0.03)/m0, and μh=8.2±1.8 cm^2/V s, respectively, at 100 K.
