Abstract. Photochromic polymeric thin films have been prepared by vacuum co- deposition of polytetrafluoroethylene (PTFE) and thermally irreversible photochromic compounds: the cyclopentene derivative of diarylethene and fulgimide. Their photochromic properties were studied using the spectral-kinetic method as compared with polymethyl methacrylate (PMMA) films filled with the same photochromic compounds prepared using the spin coating method. The films prepared using co- deposition in vacuum are characterized by photochromic properties acceptable for recording media for 3D optical memory.

Keywords: photochromism, diarylethene, fulgimide, co-deposition, spectroscopy, optical memory.
