Abstract

In this research project will be produced thin films (nanometers thickness) of a perylene derivative, bis (phenethylimido) perylene (PhPTCD) . The films will be produced by physical vapor deposition (PVD), via thermal evaporation under vacuum, enabling the growth of the film with different thicknesses in the nanometer range. Many organic electronic devices have thin films acting as element transducer signal, evidencing the importance of this study. The initial objective of this work is to investigate the supramolecular arrangement of PhPTCD in PVD thin films, i. e., thickness control, and determination of molecular organization, morphologies in micro and nanometric range and crystallinity. This supramolecular arrangement, in addition to the physical and chemical characteristics of the molecule, is a fundamental factor in optical and electrical properties of thin film. This project will also allow the student to establish his first contact with spectroscopic techniques such as absorption in the ultraviolet-visible and infrared region, and Raman scattering, also X-ray diffraction and optical and atomic force microscopies.
