| Abstract: | The paper is devoted to the development of the light-sensitive layers in which the image with nonlinear optical (NLO), photoelectric and photorefractive (PR) properties arises as a result of the photochemical reaction. Layers were obtained by using poly(hydroxyaminoether) (PHAE) containing electron-donor aromatic amino-groups in polymer chains doped with tetrabromomethane as an acceptor. The amino-groups and tetrabromomethane molecules form donor–acceptor complexes the photoexcitation of which induces electron transfer from the donor to the acceptor leading to the synthesis of a colored polycation product which possesses charge carrier photo-generating and NLO properties. Besides, these layers are electron-transporting. This allowed to obtain light-sensitive layers for recording NLO and PR images and pictures. |
