Organic Photochromes
Only a small part of the numerous phohemical 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 phohromic effect in various systems for controlling and regulating light fluxes and for data recording. Eventually an independent trend emerged in phohemistry - the study of the phohromism of organic compounds to establish relationships between structure and phohemical behavior, the theoretical analysis of these relationships to predict structures with pre-set phohromic parameters, and, finally, the identification of suitable areas for the application of phohromism. 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 phohemistry, this monograph contains a detailed exposition of the chemical phohromes referred to briefly in the earlier editions of "Introduction to the Phohemistry of Organic Compounds" (Khimiya Press, Moscow, 1976) and "Phohemical Proces­ ses in Layers" (Khimiya Press, Moscow, 1978).
