Abstract :
Four new retinal analogs on basis of nitro-substituted indoline spiropyran were prepared and the spectral kinetic study of their photochromic properties was carried out. Specific influence of nature and length of polyenic substituents on spectral characteristics of spiropyran forms, efficiency of photochromic transformations and photodegradation was established.
