Spiropyran salts and their neutral precursors: synthesis, crystal structure, photochromic transformations in solutions and solid state

Published Online: 2015-06-16 | DOI: https://doi.org/10.1515/oph-2015-0004


This review covers investigations of spiropyran iodides with N-substituted indoline fragment, and with the pyran cycle being annelated to N-methylated pyridine ring. The schemes of synthesis of iodides and their neutral precursors, as well as results of X-ray analysis and photochemical study of the crystals of the obtained compounds are presented. Based on our and literature data, the relationship between the structure and photochromic properties has been discussed for a series of salts and neutral pyridospiropyrans.

Keywords: Photochromic spiropyrans; Crystalline structure; Solid state photochromic transformations; Correlation between the structure and properties
