Abstract. Searching new more effective materials for organic electroluminescent displays is continuing. The polymethine dyes is a class of organic materials that are very interesting for these purposes. Films of the polymethine dyes were deposited by evaporation in vacuum. Also deposited were dye-filled polytetrafluoroethylene (PTFE) films. Kinetics of growth and heating the films were observed using optical spectroscopy in situ. It was found out the influence of the chemical structure of dyes on growth and heating kinetics of the dye films. It was found that PTFE matrix strongly enhances dye stability.

Keywords: polymethine dye, thin film, vacuum deposition, optical spectroscopy.
