Thin films of spirobifluorene-type materials, namely, spiro-octo1 and spiro-octo2, were investigated by means of spectroscopic ellipsometry in a broad spectral range from near-infrared to vacuum ultraviolet. The optical response of the amorphous organic films was described by an isotropic layer model based on Tauc–Lorentz functions. The dielectric functions of both types of organic films were determined. The strongest light absorption occurs around 6 eV for both types of organic films. The more effective π-conjugation of spiro-octo2 redshifts by 160 meV the absorption edge compared to Spiro-Octo1.
