Title
Polyenic spirobenzopyrans: Synthesis and study of photochromic properties
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.

► Four new retinal analogs on basis of nitro-substituted indoline spiropyran. ► Structures were confirmed by set of physicochemical methods of analysis. ► We studied spectral and photochromic properties of synthesized compounds. ► Spiropyran spectral properties depend on nature and length of polyenic substituents.
