[摘要]:Spectral and luminescent properties of novel bifunctional compounds 1-3 based on indole spiropyrans and hydroxyazomethines have been studied in comparison with the properties of the model compounds 5'-substituted spiropyrans and azomethines in organic solvents and PMMA films at 293 and 77 K. Luminescence of compounds 1-3 is due to the presence of the azomethine fragment conjugated with the indoline ring of the spiropyran moiety and determining the long-wavelength absorption band of 1-3. Depending on the solvent, temperature, and the substituent, various combinations of the structures of the chromophore fragments are observed in 1-3: the imine or amine form of the azomethine fragment and the spirocyclic or merocyanine form of the spiropyran fragment.
