Aggregation, spectral features and nonlinear properties of polymolecular layers based on spirocumarinpyrans
Aggregation of merocyanine molecules of spirocumarinpyrans in solutions and in polymolecular layers was found and studied. The dependences between the aggregation efficiency and solution polarity and structure of compounds have been determined. Efficient second-harmonic generation has been observed...

| Zusammenfassung: | Aggregation of merocyanine molecules of spirocumarinpyrans in solutions and in polymolecular layers was found and studied. The dependences between the aggregation efficiency and solution polarity and structure of compounds have been determined. Efficient second-harmonic generation has been observed for polymolecular layers containing J-aggregates. |
