The photochromic properties and aggregation processes of merocyanine forms of indoline spiropyrans of the coumarin series in solutions were studied by spectral and kinetic methods. Photochromism of the compounds synthesized depends on their structure. The efficient formation of J-aggregates was found for indoline spiropyrans 1à,b under UV irradiation and merocyanines 3à,b, which is indicated by the appearance of absorption and fluorescence bands in the visible spectral region and the resonance character of fluorescence.
