Development of the novel imaging systems requires application of new recording media in particular photochromic materials which provide the fast and reversible write-erasure of information in real time under laser irradiation. The thermal irreversible photochromic recording media providing unlimited life-time of recorded information are of prime interest for information technologies. These materials exhibit reversible transformation between two spectrally different forms under irradiation only. This paper is devoted to the analysis of own results in the study of photochromic and functional properties for more 100 synthesized photochromic compounds from three classes namely dihetarylethenes, fulgimides and phenoxy-derivatives of quinones. The dependences between properties and the compound structure have been revealed. The best photochromic compounds were used for preparation of photochromic polymer recording media. It was shown that readout of information may achieve by using a photoinduced change of optical density, fluorescence and refraction index. The received results demonstrate that the developed photochromic recording media may be used for increasing information capacity of optical disks for working bitwise and frequency-selective optical memory, photocontrolled devices for page forming and frequency switching, photographic masking, et al.
