Properties of thin porphyrin films on semiconductor surface for use in electronic devices are investigated. Thin porphyrin films were prepared via three different synthetic routes. Different optical techniques are used for investigation of their optical and structural properties. Atomic force microscopy, UV/vis and infrared in-situ ellipsometry are used to obtain information on their optical constants, layer thickness, interactions between molecules, mechanism of reaction and structural changes. Spectral information is obtained with IR reflection spectroscopy and IR ellipsometry. Vibrational bands are analyzed with respect to the chemistry and structure.
