7-Nitro- and 7-aminosubstituted spiropyrans of 1-benzothieno[3,2-b]pyrrole
摘要:
Amino and nitro derivatives of spiropyrans based on 1-benzothieno[3,2-b]pyrrole were synthesized employing an efficient method for the reduction of nitro group in thienopyrroles and spiropyrans Novel. bi-functional compounds, containing salicylideneaniline and dithienylethene fragments, along with spiropyran were prepared from the aminospiropyran derivative.

Nitro-substituted benzothienopyrroline spiropyrans containing substituents in the ben-zothienopyrroline moiety were synthesized. The comparative spectral kinetic study of the pho-tochromic transformations of these compounds and their indoline analogs in solvents of various polarity was carried out. On the basis of the results obtained and literature data, the photoin-duced aggregation of molecules of the merocyanine form in weakly polar solvents was suggested.
