The review is devoted to spiropyrans in which the pyran ring can be opened reversibly to give a completely conjugated colored isomer. Methods for the preparation of spiropyrans from various heterocyclic systems, their chemical properties, and the effects of various factors on the relative stabilities of the spiropyrans and the isomeric merocyanines are examined.read more

Development of molecular photoswitch with very fast photoresponse based on asymmetrical bis-azospiropyran
TL;DR: A novel asymmetrical bifunctional bis-azo spiropyran photochromic dye was designed and synthesized and the largest molar absorption coefficient in merocyanine form, quickest response to light, and highest fluorescence quantum yield were achieved for the asymmetric bis-azospiropyrs.
