Dye-polyelectrolyte layer-by-layer self-assembled materials: Molecular aggregation, structural stability, and singlet oxygen photogeneration

The interaction of rose Bengal (RB) and fluorescein (FL) with poly[diallyldimethylammonium] chloride (PDDA) was studied in layer-by-layer self-assembled thin films and in solution. The spectroscopic behavior is explained in terms of dye-dye, dye-polyelectrolyte, and in solution, dye-solvent interact...
