描述Only a small part of the numerous photochemical reactions in organic compounds result in reversible structural changes. The latter are accom- panied by a change in physical properties, in particular, of electronic spectra. It is tempting to try to use this photochromic effect in various systems for controlling and regulating light fluxes and for data recording. Eventually an independent trend emerged in photochemistry - the study of the photochromism of organic compounds to establish relationships between structure and photochemical behavior, the theoretical analysis of these relationships to predict structures with pre-set photochromic parameters, and, finally, the identification of suitable areas for the application of photochromism. This monograph summarizes the results of recent studies carried out by a number of research institutions in the USSR and the GDR. Devoted to an important aspect of applied photochemistry, this monograph contains a detailed exposition of the chemical photochromes referred to briefly in the earlier editions of "Introduction to the Photochemistry of Organic Compounds" (Khimiya Press, Moscow, 1976) and "Photochemical Proces- ses in Layers" (Khimiya Press

Photochromic Compounds with N=N and C=N Chromophores,n .-isomerization [1–3] and is light-induced in both directions. The special features of systems incorporating N=N and C=N bonds, as compared with iso-π-electronic systems with the C=C bond, are attributable to the presence of an unshared electron pair on the nitrogen atom.

Luminescence of Photochromic Compounds,he starting compound and the product. These limitations are of a fundamental nature. It is possible to increase the sensitivity of a material if the image obtained is detected not by the light absorption of the photoproduct formed but rather by its photoluminescence. It is well known that luminescen
