SiO₂ matrices with PM1, PM2 and PM3 polymethine dyes are synthesized. The dyes PM2 and PM3 are found to form H-aggregates and dimers, respectively, in aqueous solutions. PM1 dye forms neither H-aggregates nor dimmers due to peculiarities of its structure. The luminescence maximum of PM1 dye in the m...
